You stated you have a solid anchor point. That anchor point is determined not byjust where you place your release hand or kisser button or whatever you use to locate the string end of your draw to a consistent place.

If the draw length of the bow is longer than your body's draw length, you are not holding the bow in the same position each time and are instead compensating byallowing your bow hand to move into a natural position(locked), or somewhere close.

A shorter draw lengthwill force your elbow out and away from the bow, thus preventing string sting.
