Gibblet you are exactly right and when shooting properly how can one control anything once the string is released. In that minute time frame the bow, the body simply does what it does however and he can correct me if I'm wrong, he continues the shot "Post arrow release" which in reality means nothing because the arrow is gone....it's more a mental practice put into muscle memory which has no bearing what so ever on the arrow because it's already in the target....remember, shooting a bow is 90% mental if not more...a shot is made or missed in the mind first, the body follows suite.
I've actually never read someone putting what you said down in typing and I hope more get the chance to read it and improve their shooting ability. Course, I don't read books either.
