If one fool... aside from us competing with fortune cookie aphorisms, the FAI is taking a different look. Honest folks can differ. USA competitors always sound excited when going. Eager to complete.

I considered it a great honor to represent the USA in 1996 and 2010. I thoroughly enjoyed both trips, and wouldn't trade the experience for anything in the world. That doesn't make Doug, Ted, and Brett's comments any less accurate.

Perhaps in Europe they felt it impossible to enforce BOM. Or there was a general tendency to blur the definition using prefab quality parts. We see that here in the USA. As for weighting the value of the maneuvers according to perceived difficulty- I believe gymnastics is scored that way. Honest differences of approach.

Lots of interesting replies.

I too have represented the USA numerous times and also feel honored to do so. It is an experience not  to forget.

It is interesting that there are usually 25 to 30 countries competing in the F2B world championships. It is just not possible to have a judge from every country at every championship. Further, if every country supplied a judge it would take 5 championships to get them all ONE chance to judge (30 ÷ 6= 5).

Further, there are other considerations, such as cost. In Bulgaria, all the judges were european except for Joan. I understand she was allowed to judge as she paid her way there! This cycle sounds much the same. €€€€ is driving this, not a desire to "exclude" some judges.

Will this make a difference? Don't think it will too much. The FAI judges have now locked in on corner radius, and judge tighter corners higher. With the K factor, if you don't do tight corners you have no chance. There are still bottoms, intersections, and then shapes. I believe that is the order of importance for scoring, and is what I tried my best to do in FAI.

So, I don't think this is a slap in the face to the US, nor will it matter too much to our success.

So, US pilots, forget about this and do YOUR job and fly the best you can! Make us proud....who ever will be on the US team!!!

I guess I didn't express myself well. I know there is no BOM at the World now.   My thought was that there was a BOM stipulation at the World at one time that was subsequently abandoned. If there never was a BOM requirement at the World, I was mistaken.

I believe the BOM rule was eliminated from FAI rules in 1992. If that is true (somebody can correct me if not!), earlier World Championships would have required BOM.

Randy

I do not think there were ever Pattern Points in the FAI F2B rules.  Also, I agree with Paul that I do not think there was ever a BOM rule in F2B.

Regarding Pattern Points, the penalty for not completing a maneuver in F2B is probably considered enough of a down grade that does not require the additional loss of any Pattern Points, if there were Pattern Points. 

(This brings up the senseless double penalty in our AMA PA rules for a single mistake in a maneuver.  An error in the maneuver requires the award of a minimum score - 10 points for the maneuver- and then loss of pattern points.  And our AMA rules were "refined" over the years to insure - incorrectly in my opinion - that this double penalty would occur.  AMA CLPA rules maintain pattern points and the potential loss thereof as a holdover from the early days of CL Stunt when completing the pattern was considered a real accomplishment.  I apologize for deviating from the subject of this thread with this parenthetical insert.)

Hi Bill,

I do not think the FAI ever had a BOM for F2B.  As early as the late 60's when I first got involved with FAI F2B matters, I do not remember that there was ever an F2B BOM.

At least, the FAI does have a BOM rule for all of the scale rules for which they have various categories.  Their rule states, in part:

"Scale models must be constructed and finished solely by the competitor."  Their rules go into a lot more detail, but that is the basic wording.

Regarding Pattern Points...

Pattern points serve to give tabulators exercise.  Several times per contest I have to go out to the judges and ask why one judge awarded pattern points and the other didn't.

When I attended the WC as a spectator in the 1960's, as my memory serves, there was a BOM.  I'm also fairly sure that at least the first time there was a concours and an award of appearance points.  Not sure whether those points figured into the flight score or a separate award but do remember the judging and the discussion over the airplanes.  There were of course some language barriers for me but most of the people I was with spoke English very well and I was fairly fluent in German and could get along in Italian.   I don't remember the precise years (Heck, I can't remember what year it is now half of the time) but it had to be twice between 1962 and the end of 1967, because I went to Vietnam in January 1968, just in time for the TET Offensive!

... Also, I agree with Paul that I do not think there was ever a BOM rule in F2B.

I have spent some time researching this issue and the following is true:

There has been a BOM rule in the FAI rules seemingly forever, until changed between 2016 and 2017. The pertinent section is this, from several older documents:

1979 Sporting Code, what we call the ABR:
Quote
2.3.1     Competitor
The competitor named on the entry form must be the builder of the models entered.
Note that there is no provision for a discipline to vary from this rule as there is in the rules up through 2016, and the 1979 F2 rules do not specify that paragraph 2.3.1 does not apply for any of the four disciplines.

I do not have (or at least haven't found) an ABR and F2 rule-set for 1990 or there-abouts, but a report I wrote on the 1992 World Championships in Hradec-Kralov ssaid this:
Quote
"...This, coupled with the FAI's decision to eliminate the "builder of the model" rule resulted in many teams with..."
My conclusion is that the rules changed to no longer require the BOM in the F2 events (probably) occurred for the 1992 season.

For information, the 2016 ABR states the following:
Quote
B.3.1.  Competitor
Unless stated otherwise, the competitor named on the entry form must be builder of the model aircraft entered.
and the F2 Sporting Code for each of the four disciplines states that B.3.1 is not in effect for that discipline. IOW, no BOM.

The 2017 ABR (no longer called "the ABR") states:
Quote
C.5.1.2   Builder of the model
It is not necessary for the competitor to build his model unless the requirement to do so is specifically
stated in the rules for a particular class.
and the four disciplines have been changed accordingly.

As you can see, history says that there has been an FAI BOM rule and that it applied to all four disciplines, at least until the early 90's. I suspect the change at that time was to admit that many, many competitors did NOT build their own models, and rather than create a large amount of angst, the FAI simply did away with the BOM rule. I also believe that for F2B this was not a concern since at that time, and for many years after, there were no commercially available models of the caliber needed. But such was not the case in the other disciplines.

I didn't think so.  I have never heard of one in my time paying attention, BUT  I do not  go back that far when it was started  so, Maybe someone who does will  chime in who knows,  maybe , way back there was a  BOM  and  points for the airplane finish

    As a reader of almost all model magazines, my memory is that there was a BOM rule and the elimination of it started with the free flight classes, especially the power classes, when things started to get real high tech with all the different folding props, bunting maneuvers, and other adjustments that required a lot of special equipment and models built to take advantage of them. Pretty much what Bill quoted above, but I couldn't quote exact dates, just "back in the day."

Here is my hypothesis, based on no data,  on why the FAI did away with builder-of-the-model rules.  Long ago, if I remember correctly, all international control line events required competitors to build their own models.  Back then there also existed a peculiar institution called the Soviet Union.  Model aviation was a big deal in the Soviet Union, with state sponsorship and professional modelers.  I spoke to one young modeler who was deciding whether to become an engineer or a stunt coach-- equally viable professions in the Soviet Union.  When the Soviet Union went out of business, a couple of things happened to competition modeling there.  Each former-USSR constituent country could then send its own team to world and European championships, and the professional modelers became unemployed in the market economy.  The European modeling community then had two components: Western Europe, where people had plenty of money, but no time to build airplanes, and Eastern Europe, where people had the technical skills to build airplanes, but no money.  The solution was to have the Eastern Europeans build the airplanes for everybody, and then everybody would have airplanes and be able to afford to go to contests.

There MAY have been there, but nodody abided by it. Many times at a WC, someone would loose a plane and then fly someone elses plane. Happened frequently.

In terms of US pilots, it happened in 2014 with Kenny Stevens. He ended up flying a Kaz plane.

It also happened in Australia in 2016.

Bill showed the rule was "modified" in 2017. I guess nobody cared about following those rules.

My first contest under FAI rules was back in the late 60's in a State Championship which I happened to win. I used a model I bought some time earlier. Later I was a judge in the 73/74 Christmas period Nationals. In all that time there was never a BOM rule and certainly never a beauty pageant either.

Well, perhaps not in the late 60's but there definitely was in the early and middle 60's.

I saw it happen!  Was anyone else at the early middle 60's WC's.  I was stationed in Europe at that time until late 1967 and traveled throughout all of the Nato countries for communication center business and other situational things and saw and heard BOM rules discussed etc.  They were used!  I do suspect that they weren't very well enforced and a lot of "cheating went on".  They finally just gave up and ignored the situation.  Sort'a like my posts on this thread!

Paul, I suspect you have identified exactly what the situation was back in the 80's and earlier: there WAS a BOM rule then, and nobody paid any attention to it.

As I said, as far as I can tell without actual FAI documents (ABR and F2 Sporting code) from the period, the BOM for F2 was done away with in 1991 or 1992. The events with Kenny and others since then are completely within the rules that were in effect at the time.

As for the 2017 changes: it was simply a re-wording of the way the rule was written and no real change to the rules.

Bottom line: BOM WAS an FAI rule for F2 until about 1992. The fact that it was ignored before doesn't alter the fact that it was there.

From my earlier post:

Keep in mind, too, that the 2017 versions are worded differently, but still no BOM for F2.

It's probably good that the FAI did away with the BOM. They haven't grasped the concept of cutting grass for a European Championship, so enforcing a BOM would be a bit of a stretch.

Well, kinda.......
Previous to 2006, F2B was all flown on a single circle and I am not aware of any grass circles for official flying. Yes, a grass practice circle possible. Of course, we tried to get the FAI to allow the 2-circle format in Muncie in 2004, but even though the rules were changing to allow it later, we had to follow the existing rules then.

In 2006 in Spain, there was one paved circle and a grass circle in a local football stadium. (Please correct me if I'm incorrect.)

Not sure what they did in 2008 in France although I suspect the same: one paved, one grass.

Now, 2010 was a mess with two unfinished grass circles.

In 2012 we were in Bulgaria where they had a brand new flying site, but only one paved F2B circle, the second grass, and that being totally unfinished with a very bad surface. I'm sure DavidF can tell some horror stories about that!

And then 2014: another disaster with mowed pasture off the edge of the airport for the two circles.

2016 in Perth was beautiful with two new asphalt circles specially prepared for F2B.

The bottom line (again) is that there are few places in Europe which have an existing site with sufficient paved circles, and the new sites, while perhaps someday, as well. Of course, we would like better, a "Muncie everywhere", but that will not happen. The only saving comment is "All of the competitors face the same situation."

The question that has been raised: do we accept a site that is not Muncie-quality or do we cancel a World Championships otherwise?

I always struck me that the FAI's elimination of the BOM coincided with the end of The Cold War, thereby enabling Eastern Bloc manufacturers to sell their products worldwide.

While eliminating local craftsmanship, it has provided everybody with the same world-class equipment, subject only to final adjustment.  We have more flyers now than we had under the build-and-fly regime.

With reorganization of the USSR, Czechoslovakia, Yugoslavia and Germany, we now have 25 nations in the place of 5.  This further diluted any influence the USA might have had left us with choice of taking the FAI's policy or leaving it.  Based on F2 participation, a goodly number of Americans have decided to go along with the system.

Previous to 2006, F2B was all flown on a single circle and I am not aware of any grass circles for official flying. Yes, a grass practice circle possible. Of course, we tried to get the FAI to allow the 2-circle format in Muncie in 2004, but even though the rules were changing to allow it later, we had to follow the existing rules then.

In 2006 in Spain, there was one paved circle and a grass circle in a local football stadium. (Please correct me if I'm incorrect.)

Not sure what they did in 2008 in France although I suspect the same: one paved, one grass.

Now, 2010 was a mess with two unfinished grass circles.

In 2012 we were in Bulgaria where they had a brand new flying site, but only one paved F2B circle, the second grass, and that being totally unfinished with a very bad surface. I'm sure DavidF can tell some horror stories about that!

And then 2014: another disaster with mowed pasture off the edge of the airport for the two circles.

2016 in Perth was beautiful with two new asphalt circles specially prepared for F2B.

The bottom line (again) is that there are few places in Europe which have an existing site with sufficient paved circles, and the new sites, while perhaps someday, as well. Of course, we would like better, a "Muncie everywhere", but that will not happen. The only saving comment is "All of the competitors face the same situation."

The question that has been raised: do we accept a site that is not Muncie-quality or do we cancel a World Championships otherwise?

1996 was on an asphalt runway, and was a good contest from what I remember.

I don't think we should call off world champs because the places might not be as nice as Muncie, but I do think that countries that put in bids, should at least make sure they can provide an adequate site. The site in Hungary could be nice, it's an open field with lots of room. They should start cutting the grass, weekly, a month before a competition. A few shovels of dirt, in some of the holes wouldn't hurt either. It wouldn't cost much, but someone would have to be willing to do the work.

Maybe you haven't seen... It was my reason for the grass cutting comments.

There are many unhappy contestants at the European Championship. The conditions are much worse than when we were there.

Check out their posts on facebook. They are flying off a "pasture". Their words, not mine. No thought appears to be  given to F2B needs.

For the record, I can add a bit of detail to the two championships Bill mentioned above.

2006 in Spain.  The Championships were held at a permanent site operated by a local model group.  Single paved circles were available for Speed, Stunt and Speed.  The stunt circle had a fence next to a good portion of the outside of the circle such that there was not enough room for judges to stand if the wind was in the wrong direction.  For qualifying rounds, a soccer field was used that needed to be mowed at least twice a day (it wasn't).  The grass may have been great to play soccer but landing became a problem for many competitors, particularly since the judges did not take into consideration (as they were supposed to do) conditions affecting the landing that were beyond the pilot's control. This did not impact any of our team members from qualifying for the Finals, but in at least one case, it could have been a factor.

Poland in 2014 is a different story altogether.  As Bill mentioned, the two circles used for the qualifying rounds, and one of these became the one used for the finals, and another to be used for practice were mowed just before the beginning of the World Cup which just preceded the World Championships.  I have not written of this before out of courtesy to the host country.  But those circles were carved from a large coarse weed and a sort of grassy area next to an active runway that would be an insult to a cow pasture.  The poor surface was a direct cause for Kenny Stevens crashing his model on a practice flight just before the competition was to start.

     I am no longer interested in trying to resolve these problems out of extreme frustration, but a few points.

     Some of the "traveling NATs" sites were less than ideal in the AMA, as well, for mostly the same reason - it's very difficult to find hosts that have all the ideal conditions, even for the 4 events in FAI, much less the 50+events for the NATs. Additionally, most people in the US don't realize that on an international level, there is more interest in TR than there is in stunt, and many of the organizers have very elaborate TR circles at these sites. We care about the stunt site because we are stunt fliers and because it is the dominant event here and only a few have ever even seen FAI TR,  but it's not the same everywhere.

     TR also fits the incredibly delusional/insane vision that a few hold of "Model Airplanes in the Olympics" much better than stunt. If that gets in the Olympics, I will lobby for Wii Bowling or Gran Turismo simulation racing, too, because it makes about as much sense and has an equal chance of actually happening. 

    Additionally, there is at least some idea (relayed to me by one of our European stunt friends who wishes to remain anonymous) that the 2-circle format makes no sense and they want to make it look as bad as possible, both because we (USA) largely championed it, it costs more since you have to have many more judges, and because the obvious solution (only hold WC where they have enough space to have two paved circles and some practice) eliminates many of the potential European hosts. So you would end up going to far off distant regions like Australia and even worse, the USA, on a regular basis. Again, I think Perth is closer to the center of the Earth than is Landres, but they can't toss their airplanes in the back of the car and drive to it in a day. Note that even the 2-circle format is a severe compromise for the number of competitors, and it runs about like our Team Trials qualifying.

    My suggested compromise was to *take the required contest format out of the rule book*, which permits the *format* to be adjusted to suit the available facilities/budget, etc. That certainly doesn't meet the needs of the bureaucrats for hard and fast rules, and reduces the needs for the existence of bureaucrats at all. Someone might lose face if say, we hold a 4-circle qualifying in Muncie with everybody done by 2 in the afternoon, and then a 1-circle trudge to oblivion in, say, Landres.

   The FAI stunt fliers (i.e. the people we know and have heard of) know most of this, and are just as frustrated by this situation as anyone else, and if they were running the show, this would not be a problem. But they aren't running it.

   Of course, no one sets out to screw up, and I am sure that to first approximation, they try to do the best they can, but at the end, it hasn't been working out.

I would ask if you're joking....... but, .....
Amazing that a WC event gets flown off grass.

     A lot of people back East are surprised by that, but in California, we fly most of our contests, even the big ones, off of grass. The Golden State meet was held on various football*, soccer, and baseball fields around Fresno/Clovis and Gilroy. Only recently has it moved to the EXCEPTIONAL site at Madera (which would be a DANDY place for a TT, too). But the grass is usually well-groomed and in some cases (like the original Clovis High School site) was a like a golf green. The 600x600 pad at Muncie, when it has been prepared correctly as it has been in recent years), would probably be preferable to me to the L-Pad because if nothing else, it's a lot cooler.

    But as Keith notes, if you don't prepare it (and in many cases, also prevent the competitors from going out and buying a mower to mow it themselves), it can be a real tough go. Kenny wrecked his airplane at least partly because of it, and despite people having cautioned him about it before they left. It's a darn shame and I know that many stunt fliers from around the world have been frustrated by this situation time after time.

    Brett

Just a note here about the number of judges.  The single circle format for the World Championships used 5 judges.  The two circle format now used for the World Championships requires 6 judges - 3 judges per qualifying circle, then all 6 judges for the finals.

The problem with the two circle format chosen by the powers still requires up to 3 days with 40 to 50 flights per day (50 flights per day is the maximum allowed) for all of the judges during the qualification rounds.  Actually, there is little or no relief or reduced workload for the judges going to the two circle format now used for the World Championships.  So, instead of 5 judges suffering through the qualification rounds, we have 6 judges doing so.  The only "improvement" by going to the two circle format is that each competitor gets 4 flights, using the best flight from each of the qualifying circles to get into the top 15 finals.  Before, a competitor had 2 flights during the qualification round, using the single best flight to get into the top 15 finals.

Also, keep in mind, the format used for the World Championships is different than other FAI F2B contests where single circle format is specified per the FAI rules.

   No, that is not the only improvement. The more important improvement is that the rounds are shorter, so even though the overall loading on the judges is the same, the time spent in each round from beginning to end is shorter, and thus less effected by any ballooning, weather changes, etc.

     The flaw with the single-circle format was illustrated in droves by the 2004 WC in Muncie. Ted flew #1 on Tuesday morning, and that same round, was compared with the same absolute score from nearly *36 hours* later, late Wednesday afternoon. The weather wasn't the same and the judges had had two full days to ballon. It was even better illustrated by the second round, when after almost 4 full days, suddenly on Friday afternoon, the wind dropped from very difficult at the beginning of the round on Thursday morning, to nearly ideal starting around noon on Friday. So anyone who flew Friday afternoon got whatever ballooning you get after nearly 4 days of standing in the sun, PLUS, ideal conditions. Yuri Yatsenko flew his second round flight on Thursday morning in the worst of the air, that was compared to someone in the Friday afternoon with ideal conditions, and of course, he didn't make it. Most of the qualifiers flew on Friday, might as well have not bothered with the other rounds. So in some ways, at least a few positions in the finals was decided at random.

    If you want to argue that 2 isn't enough, then I would agree, and you would get a tremendously bigger advantage using 3 (ideal since there are 3 team members) or 4 (so you could run it like the NATs), and keep the round length shorter. 2 was a grudging compromise between the ridiculous "everybody on one" and the proper "as many as you want, but at least 2" that I proposed. Divide the groups just like at the NATS, make it "n" independent contests, just like the NATs, then run the finals like they have always done (like our Top 5 day except with 15 pilots).

   A far better solution would be to limit the rounds and the comparison of one flight to another to about 4 hours, which if you allocate 10 minutes slots, is groups of 24, then divide it into however many qualifying groups it takes, typically, 4. Then run it exactly like the NATs qualifying.

Brett, I am not arguing with you, but when I said the only improvement in going to a 2 circle format is that pilots get four qualifying flights is better than two qualifying flights is basically what you said without going through all of the "what ifs" and examples of bad air/good air, ballooning judges, impact of drawing rotations, load on judges, etc, etc.  Multiple rounds and multiple circles and more of them indeed start to minimize the vagaries of any system we can devise as far as getting the best and fairest selection of pilots to move into a finals process, whatever format that finals series has.

In my opinion, the goal of any CL Stunt Championship series (National and International) is to fairly determine the best pilot and a fair and as accurate as possible ranking of all the other pilots.  Taking care of the judges so they are not required to judge 40 to 50 flights a day for several days is part of that equation.

    Well, exactly, if you ignore those things, you just get more chances and its not much of an improvement.

     But those things you ignore and call "what ifs" appeared to have time and time again been a very strong driving force in the results with the one-circle format and needed to be addressed in some way.

    I will also grant that this system still asks for/demands borderline abusive work loads for the judges. I would suggest it's better than running from dawn to dusk for two straight days with them trying to tell themselves "don't balloon" every 8 minutes, but it's certainly not ideal.

    I proposed that you could kill two birds with one stone by cancelling the "World Cup" event preceding every recent WC. This contest, which permits the WC competitors and judges alike to participate, amounts to a pre-judging contest since it's patently impossible for the judges to not know who did what - and of course, decide where they might have made a "mistake", to be "corrected" during the WC, consciously or not.

  What you could do, instead, is get rid of the Pre-judging contest, er, "World Cup", and extend stunt qualifying over the time now available. Everyone is there anyway (because it is quite obvious that if you don't enter the World Cup, might as well not go to the WC, either), so make it count for something. That way, you do 4 hour rounds with 4 or more groups, not even bother with trying to get both groups on the same day since you are only flying against the others in your group per standard Nationals procedures. Everybody gets a good night's sleep, no one is driven to exhaustion, problem solved.

      I proposed this several times, but all I heard was crickets the first time, and people sending me messages about how fun World Cups are for everyone the second time. No doubt this is true, but I again thought the purpose was to crown the world champion, not have fun-flies.

     Certainly agreed there, and I argued long and hard to at least permit if not require MORE than two circles, and various international experts had a hissy fit over it. The compromise was two, which is better than one, but not nearly as good as four. I suggested all the superior methods and no one was willing to go along. If I was the Dictator of the World, it would be fixed, but people made a good-faith effort and this is what we wound up with.

   Recall that these are the same people who wanted to run without K-factors as "an experiment" despite the 50+ years of experience and them not having been present in the rules that they ripped off from the AMA in the first place. And then considered such an "experiment" too risky to actually try!

   If you want to try again, I will certainly back you up, but no one is listening, for whatever reason. Try to fix the other issues, too, specifically the K-factors (which are taking the random luck weather and judging variations and multiplying them by 18), and the 1/2 point problem, too. We haven't had any luck with that in the past, but maybe it will be different. I can think of another solution, and one that I have some control over - go to the NATs instead.

Absolutely. This brings us full circle to why Derek was so frustrated, and I have had my fill, too.

  Forget for a second where it is, or what the stakes might be.

     If you want the best, fairest, and most accurate results, you need the best judges.  You need to put them, and the competitors, in the best and most fair conditions that can be devised.

   There are a lot of very good judges around the world and it makes sense to use those best judges for your world championship.

   If you want to put those judges in the best position to be fair and not demand unreasonable work and consistency, you need a multi-round format, on the order of 4 groups for the number of entrants they usually get. The purpose would be to hold the round length to than 4 hours or less, and not compare one group's scores directly to another to accommodate the high judge/low judge effect, which I contend is otherwise unfixable (and is not really a defect).

   If you want the scores to be as consistent as possible, you need to have sufficient resolution in the scoring system to remove the effects of quantization errors.

   If you want the competitors to get the best shake, you put them on the best possible fields and in the best possible format to show their skills and not get burned inordinately by random effects like weather that you cannot otherwise control.

   At the US Nationals, we have ALL of these items addressed in some way, because everyone else from about 1949 on has had exactly the same goals you expressed above.

   At the WC, we routinely have very substandard contest formats (although improved from previous examples), driving judges into abusive conditions with unreasonable expectations of consistency. The same format issues maximize the chance of the pilots being disadvantaged by the random weather variations. The scoring system is heavily quantized, then multiplies any quantization error by large gains (up to 18x) massively increasing the system "noise".

    There are frequently ridiculous facilities in which world-class modelers with decades of experience end up damaging their airplane trying to fly in conditions we wouldn't accept at a Class C local contest. We have people with nearly no experience in running big-time stunt contests advocating for poor scoring systems and ridiculous format limitations, primarily because they want to hold their supposedly world-class event in a cow pasture, (or as Serge put it "a potato field"). We have contest organizers that won't properly prepare the sites, and go out of their way to prevent anyone else from fixing it, too.

    We have people complaining about the really good WC sites because they are somehow "too far away" from the "world" they are supposed to be representing. We have very sharp international stunt fliers (Serge Delabarde, Peter Germann, Andy Sweetland, and many others) and organizers who recognize and try to fix these issues, to be systemically thwarted by meddling one-world bureaucrats and self-important out-of-touch graybeard committees who decide everything behind closed doors with no recourse for correcting their mistakes.

   And now, we have the host country deciding NOT to include some of the best and most experienced judges, for no adequately explained reason.

   So, there appears to be NO attempt to create the most objective and fair contest; in fact, it appear to be some sort of "compromise" half-assed system that doesn't consider getting the right answer as the highest priority.

   That's why everybody is pissed off, and not asking or rejecting someone of Mark Overmeier's stature is just the last straw. They aren't even trying to put on the best contest, or get the most accurate results.

Absolutely correct!

As a top five pilot, I almost feel that it is my duty to represent the US in world events. Paul and David have certainly put in their fair share of time and money, and both of them have been rewarded for their efforts. They are done now, and I can't say I blame them. So here is my dilemma; do I try out for the team, travel to another European Championship where the favorite has been previously selected, risk my airplane (that I have years of building and trimming invested) for a shot at 5th to 20th place, or do I try to win the most prestigious trophy on the planet? That would be the Walker Cup for those of you in Rio Linda.

I do wish some of those top guys in Europe would skip the WC, and bring a BOM legal plane to Muncie....

    Well, exactly, if you ignore those things, you just get more chances and its not much of an improvement.

     But those things you ignore and call "what ifs" appeared to have time and time again been a very strong driving force in the results with the one-circle format and needed to be addressed in some way.

Brett,

Again, I am not trying to argue here.  But I am not ignoring the many factors as you accuse by using the "what ifs" term being discussed here.  What I am saying is that when I mention using multiple circle format that it starts to minimize the many "what ifs" being discussed here, and not ignoring them.  We are saying the same thing, I just combine it all with using the probably over simplification term of "what ifs".

I am not sure what you mean by the "1/2 point problem".  The FAI F2B scoring system has always been based on a 1 to 10 point spread.  Some time ago, the scoring was done in 1 point increments.  Then, the system was revised to use scoring in 1/2 point increments which was a significant improvement from that used previously as far as giving the judges a more refined tool to score a maneuver.  Then, when the major rewrite of the F2B rules was incorporated several years ago, scoring with 0.1 point increments was incorporated and is a far better system for the judges to use.

Something has been mentioned in this thread about not using high and low scores.  Sometime, either just before the 2 circle format was adopted in the FAI rules for World Championship competition or at the time the 2 circle format was adopted, a study was made at the request of a member of the CIAM to analyze the concept of eliminating the high and low judges' scores in the tabulation process.  The study included the results from several world championships.   I do not have the details, but basically, the analysis showed that using or not using the high and low scores for each flight really did not change the outcome of the overall placing of the individual pilots.  The top fliers' placings remained essentially the same in both systems.  In some cases, there might be some changes in the lower place, like who was 4th and who was 5th, but in all cases, the champion remained the same.  Anyway, all judges' scores now are used to determine the average score for each individual flight.

And let's not get into the matter of using or not using K-factors for the F2B event.  However, I will comment that the suggestion that other judged activities, like diving and gymnastics, effectively use K-factors and can be a definite/important factor in the outcome of those competitions.  This argument does not apply to F2B as K-factors in those other activities apply to optional tricks available to the competitor with the attendant risks involved with the more difficult tricks.  When all competitors perform the same schedule, the K-factors being used in F2B places an undue and unwarranted premium on certain maneuvers.

   Then I am not sure what point you *are* trying to make, because I have carefully read your "corrections" to my posts and I can't figure out what you are getting at. I know you have a point, you always do (and it's usually valid). Maybe it doesn't make any difference...

     If your point is that for a WC event (or really, any contest with ~100 entrants), you should run a multi-circle format with about 25 per circle, then we are in perfect agreement. If your point is that the 2-circle format is not as good, also agreed, and that's a point I tried to make over and over again when this debate was going in the early-mid 00s.  We have long since agreed that the former 100-people-on-one-circle was utterly laughable, ridiculous even.

    I also agree that the judge workload is not much if any better with a two-circle format, another point I made at the time (to no effect, of course). What *is* an improvement is that the effect on the results of the judge exhaustion and other random factors like weather IS improved by doing it this way. Not as much as it should/could be with a proper format, but better than the old way.

     If your point is that we shouldn't accept these sorts of compromises for a contest someone chooses to call a "World Championship" (nor the other ones like flying in cow pastures), I think you have validated the entire thread, because certainly I think that and Derek seems to think that. It's time to either fix it or move on. Based on what I have seen, there is *no* fixing it within the FAI system, it's not possible.  This despite everyone involved in international stunt more-or-less agreeing on where the problems lie and what most of the solutions are.  I have been working (starting as your behest, as I recall) for more than 20 years, we know what to do, and yet no one seems able to move forward.

   This last is the end of the road for me. I have better things to do with my time than to try to solve something in a system that ignores the best evidence and best practices due to unknown entrenched interests or bureaucratic inertia, or simple lack of focus on improvement or optimization.
