Ummm.... you push that bowarm at the target while you draw back focusing on using the back muscles. Try it, you'll feel it. When you are doing it, you will feel it in the back muscles.
All the while drawing/stretching a "line" between your bowhand and drawing arm that is the arrow.
When you reach full draw do not lock up, or set.
I think the concept of full draw to anchor point decieves folks into looking for a mechanically exact, reppeatable form.
Actually, You should be still pushing and still pulling - maintaining that "line" in dynamic tension. It feels like nothing is "set" or rigid, or locked down. Feels like the "line" is floating somewhat. It is - floating according to you vision/muscle management to direct the arrow to the spot.
When you release in this dynamic push/pull your arrows will go where you point, and your release will be clean if you use a deep hook.
Anyway, that's what I discovered works for surprising instictive accuracy.
