I was typing my last post when this one came in.
I am now sitting here knowing exactly why ChalkBucket was created. This post is absolutely brilliant!
I have nothing more to say...
Thank you emorymom!
EDIT: So many people told me why I was wrong...emorymom gave me a solution. BRAVO! Logic at its finest.
I don't get it... what if all your "B" gymnasts (or their parents) want to do the extra hours too? Wouldn't that diminish the time and effort you are able to concentrate on your "A" gymnasts? You'd be right back at having to manage different skills, sizes, etc during your practice?
Our optional coach tried this - he offered extra weekend hours to his unofficial A-team girls... when the unofficial B team parents found out, they wanted to send their kids too.. eventually, it just became a regular practice - too big to manage, too little time/coaches available to uptrain his "A" girls..
