Usually a bow will stack past the tillered lenght. Also, the lenght of the limbs and or amount of reflex or recurve put into it. Length of limbs is the biggest. This is why we pike the limbs to get more draw weight, when needed. When I make a bow that is intended for a 26" draw lenght, I tiller it to the intended weight at that draw, and if the limbs are fairly short, it will start stacking morepast that draw lenght.
