If I may... and I do see your points and respect them and agree with them in some ways... but it's not so much that they will simply "not catch".. I think it's more that they may catch unsafely, or the flyer who is executing the toss in the air may freak out (so say, it was level 6 and they did tuck baskets) and stop pulling in the inverted position and come down in an unsafe position... or say a kick double and because the music stops the flyer hears the music stop and freaks out and comes down loose, arms flailing, etc. Competition is nothing like practice. When you're on that stage, everything is such a rush, between the adrenaline, lights, loud music, the crowds, that you just don't think like you do while you're practicing. In practice you almost expect to hear the music stop at least twice during practice so coaches can make corrections. You don't expect it or listen for it during comps... it's instant confusion because most athletes don't expect to have injuries on the floor. It's always, "we got this, nothing will go wrong." mainly because we're trained to think and prepare ourselves like that. It's a completely different feeling when you're on the mats at the gym and on the mats on stage. I'm not saying that cutting music off at an unsafe time in practice is okay and that it couldn't cause injury then... I'm just pointing that out from an athletes perspective. Just my opinion.
