That is pretty good Sal.
I would say if you are shooting that good consistantly, you should have a pretty good feel if the arrow is going to hit where it is aimed at that yardage even before you let it go. And you should know if something doesn't feel right in the shot progression that will make the arrow not hit the intended target.
I would say to use this judgement in deciding whether to let the arrow fly at live game.
You know you can hit the vitals at the stated yardage, it's just a matter of does it feel right.
Oh, and never hope and pray, that'll effect your confidence.
JMHO.
