Tilz......in theory the increased power stroke of drawing the bow an additional amount would result in an arrow impact to the right(RH archer) due to imparting more to the arrow and therfore a weak arrow reaction....BUT ofthen whats happen in an overdraw situation is.....the face gets thicker farther back(when using a side of face anchor) which in effect moves the anchor( and the nock end of the shaft) to the right...which points the arrow to the left, resulting in a left impact. Under the chin anchors almost always get an right arrow impact when overdrawing the bow.
