RE: tip yall may or may not know
your theory would work great if it weren't for a little thing called gravity. if you want to know what yardage to shoot, all you need to do is figure the yardage from the base of the tree. if a deer is 20 yards form the base of the tree, use your 20 yard pin. if said deer is 30 yards out, use your 30 yard pin, and so on. this works.
