im not saying this is the problem but maybe the shorter brace height of the 82nd was the reason your groups were bigger. it tends to show your mistakes at the other end a little more.
Certainly even a perfectly tuned bow will have some variances, and the shorter BH will definitely accentuate any form flaws. Part of the reason I prefer a "little" longer BH, cause I'm not that great of a shooter!!!!
Good Pic, Dub, and pretty good shootin'!!!
