Well , leave out the O'Head 8 , otherwise . . .

another two here , three in total . Wonders of modern tecnology .
Moving Pictures. With Sound . S?P
Third one is a COMPARISON between entrants .
Seems to be a toss up as to wether red or blue trousers are more accurate / consistant . %^@

Hmmm... if a computer had to assign these tricks scores, it occurs to me we might have to change our scoring system to something like 100 points per trick. I say this because the resolution of errors seen is so high that using the deduction method would give everyone a zero! Hah! Of course you could program in a certain level of tolerance for track departure, but then you might get a lot of similar scores, so would have to use it in practice to see how it works out before weighting the numbers and writing final code. Still, very interesting indeed. If our event lasts long enough, and there is still enough interest by then, the technology is certainly coming for computer scoring that will be affordable to the average club.

This shows where the maneuvers begin and where they end, something not everyone is aware of....

Thus is a very complicated process.
I spoke with him about this when it first came put. He does it frame by frame and dots each point of each manouvers. Took him 3 days to do this.

If one man can do it in three days a program could do it in 3 seconds.
The scoring would have to change, probably the total deviation(areas) from the correct path overlaying the correct path from the start of each maneuver. Every modern flyer would hate it. There would be no judges to blame!
I did something like this by hand also from some videos of the top five flyoff. It was clear that one flyer took first on the basis of 2-3 extremely good single maneuvers on one flight and there were 4 flyers in second. The judges noticed and called it right.

That is really cool. y1

The tech is pretty much here today already, where you don't have to hand trace do by dot.
If any of you watch Red Bull Air Races, you see them using Dart Fish software to compare the tracks of 2 different planes through the pylons.
The new stuff from Dartfish has an auto tracker, you don't have to do it by hand dot by dot, just tag a point on an object on-screen that you want it to follow and sit back and watch.
