Some of the things you described have also happened to my daughter. The high fiving and celebrating other gymnasts for example when they finally nail their routine. She finally nailed her beam routine at their last meet and was so pumped but he barely acknowledged it which really hurt her feelings after she has busted her butt all season on that stupid routine and finally nailed it. Also the favorites slacking off has always been an issue and at times my daughter who does her conditioning and is often one of the first to finish because she isn't slacking off, is often questioned on whether or not she actually did all of the conditioning. I have sat and watched her do all of it while her teammates sit in a circle and gossip and then she is questioned and accused of rushing through or not doing all of the reps. The favorites cut the line to get more turns, slack on things they don't want to do, etc and they are never called out on it. The lack of uptraining is just the latest concern.
