I keep going back to the talent pool but when you're talking about a tryout, that has a lot to do with who makes it.
If the talent pool has solid to awesome motions and is amazing with other requirements, a coach is not going to go out of his/her way to add someone for whom motions are going to be an issue, because motions are Cheer 101 (whether or not you have ever done school cheer, a high V is still something that everyone knows.) And everyone in pool is great with them. No need to relax your criteria.
On the other hand, if the pool is AMAZING with tumbling and stunts but 90% of them are in need of Gameday Jesus, he/she is going to accept that he/she is going to have to work with what they have, take on the awesome stunters and tumblers, and DEVELOP the gameday skills.
All of that to say, tryout results depend a lot on what other candidates are doing.
