To me a good judge recognises their foibles, regards their own traits, works around them and gives a considered decision taking into account ALL the evidence.
In other words not a 'black and white' answer concerning colour (excuse the pun) but instead we get absolutes like 'LUDICROUS', 'irrelevant' and its a 'waste of time.'
It sounded like you totally discount the notion before giving it any credence by saying that it doesn't matter, yet it obviously matters, and is in the minds of those who you are judging.
No one has ever been compelled to do anything I say, if I am so clearly wrong, by all means, do anything you want. And, since it "obviously* matters, it's a great compliment to me (and Ted and David and whoever else) that I have managed to function successfully despite ignoring a relevant aspect of the hobby. And judge 10000+ flights without ever once realizing it.
The question was asked, does it matter, my *opinion* is that it does not and that the underlying logic, like you display above, can be a crippling impediment. Again, in my opinion, it is:
(1) not supported by anything I have seen over the last 40 years of intense study
(2) the thought process is an absolutely classic "trap" for people trying to advance themselves in the event. If you ever give into the (mistaken) notion that Given that anyone who can afford to travel to big contests can afford the best equipment ever available, and that no more than average physical skills are required to compete at any level, these sorts of psychological traps are far and away the biggest impediment to success. You see it all the time, it's the biggest reason that we don't have 50 people all competing at a US National/World championship level, rather than 10 or so.
My best advice (which I got from my mentor Ted Fancher, perhaps not verbatim but in concept) is that *you* control your own fate, so worrying about "what color airplane", "what color pants" - which is definitely believed to be a factor by some-, "what the judges are buying today", "getting your name noticed", "presenting better", "the judges are against me", "halos", etc, or any other factor outside your control is a distraction and a potential trap for everyone.
There are a raft of examples I could provide where people have outsmarted themselves with this kind of reasoning, some over the period of decades, and to their great detriment. I had a few cases of it myself, at a point where I was already competitive in Expert but not quite to the highest levels. Fortunately there were people around me to point it out (Ted) and get me sorted out, otherwise, I might be another of those guys our there sabotaging myself.
But as always, I can only tell you what I think, it could be wrong. A few people will probably pay heed, others will not, maybe they will be able to work through it themselves, or not.
