I believe this is probably true...or at least implied. But, are there actually rules that say an athlete cannot compete for two gyms? I know they cannot compete for two gyms at the same event, but are there rules that prohibit an athlete from being registered at two gyms? I'm not suggesting any teams did this sort of thing, but I don't think it is prohibited. Obviously a gym would need to remain under 125 to maintain D2 status...even with an additional athlete from another program.
Somewhat related...Our gym, for one competition, had teams going for d1 AND D2 bids. I was curious if you could crossover from D1 Summit to D2 (regardless of the complications, I was just curious) and I never saw a rule prohibiting it.
