you do have a point about seeing alot of the same planes and knowing, by default, that they MUST be good ones!

At the club I fly at, the last time I was there, there were FOUR T-28's! and they all got into the air at the same time chasing eachother around! I thought it was funny as heck to watch the people try to keep track of their own planes!!! When there's this SWIRLING MASS of planes that are ALL DEAD IDENTICAL, it must have been pretty easy to get confused A couple of people would just yank on the sticks to see which one "jumped" to figure it out
