really like this rule!
"ATHLETE ELIGIBILITY LIMITS: EARNING MULTIPLE PAID BIDS
Athletes within the same program are limited to the number of teams on which they are eligible to compete and earn paid or partial-paid bids. Once an athlete has competed for a team and earned a paid or partial-paid bid, the athlete is permitted to move to another team within his or her program. If the athlete's second team earns a paid or partial-paid bid, they are bound to the second team and may only compete with the second team at Worlds. The athlete is no longer eligible to compete with the first team once the second team is awarded a paid or partial-paid bid.
The number of athletes that have already earned a paid bid that are eligible to compete for and be awarded a paid or partial-paid bid on a second team is limited:
a small team may have up to 3 athletes that have previously been awarded a paid or partial-paid bid
a medium team may have up to 4 athletes that have previously been awarded a paid or partial-paid bid
a large team may have up to 5 athletes that have previously been awarded a paid or partial-paid bid"
