Ad,
Without seeing, it is hard to give other than a "theoretical" answer. It is GENERALLY accepted in the higher levels of archery coach's training that pulling back past your facial references then allowing the hand and arm to move forward makes the shooter loose back tension. AND that once back tension is lost, it cannot be successfully regained without starting the shot over again from the beginning.
Again, in general, we don't like to see someone pulling past their anchor then sinking forward to anchor. It is a recipe for a collapsing shot.
There should be a place in your draw where you feel the bones pick up the lion's share of the bow weight (kind of like feeling the let off on a compound bow) -- that should be your draw length. When you get that feeling (bone support for the bow weight)Your hand should be where it needs to be. If you draw to "bone support," with your string hand SLIGHTLY low (No more than one inch or 2 cm) then all you do is lift the hand to the face and set the references. The hand and string arm should NEVER move forward --again according to commonly taught theory.
You can see this movement in all my videos -- the draw then lift to anchor.
Another error common here is DECIDING that we want our string hand touching this place, that place and another place, arbitrarily. Your hand on the face position is a RESULT of your draw (bones lined up) and NOT just deciding that that is where the hand should be.
Again theoretical answers, really need to see a recent video to help much more.
