All good books mentioned. The problem, however, is that there are never any draw lengths or full draw profiles. And you can't always find the draw length by looking at the arrows. Many of us attempt draw lengths that are about half of the bow length, when we build these bows for ourselves, but that is wishful thinking, IMO.
Saxton Pope conducted some tests on actual Amerindian bows back in the day. Those tests yielded various results and at least one of the bows broke. But those tests are the best info we have other than experiments by people on this forum (and others).
