As of 4/5 years ago rules for 501C is that the gymnasts could not benefit unequally due to how much fundraising they each do, however, organizations can have other criteria that is NOT related to fundraising, so for example, booster club can pay for fees for girls going to Easterns/Nationals (which would only be L9/10.... or they can pay for all girls attending a certain meet, so if only 9/10s go to that meet, then that is how it goes.... What they cannot due, is limit it to only the girls/families that participated in the fundraisers. Now, that may have changed in the past few years...we are now at a gym without a boosterclub, so admittedly I have no knowledge of current rules.
