Do not think it's professional nor accurate to say to everyone wrist snaps are not helpful. They are but one useful tool applied in a sequence with much more of the body. Isolating and getting that feel has been effective for our family. To support that speaking for my daughter who is a high level pitcher, to keep her anonymity but still provide status, she plays for one of the top 25 D1 teams in the nation. With returning visits to WCWS. Does wrist snaps and always has.
Wrist snaps aren't helping her, outside of maybe mentally as part of a routine she's comfortable with. Thankfully, they haven't hurt her, so there's obviously no reason to stop it.
But since no part of actually pitching involves those wrist snaps, it's really impossible that they actually help with the physical aspect of pitching.
