Question for you experienced coaches.  At what setting in any individual practice category does the law of diminishing returns seem to kick in?  Is it 20?  I'm just curious and what level I am starting to lose some efficacy in practice.  Also, what is the highest reasonable setting for any 1 category and what is the lowest setting you can put a category at before the player will start to see some regression?  Thanks for your help.

forum fact is 20 - some think it starts to diminish before then - I act on the assumption that it is 20 in general

Thanks fd343ny

Regression is generally 7 for most categories; 3 for LP/PER; I use 8 for FT.  Not sure what it is for conditioning.
