Very interesting, many years back Jack Howard suggested a bow for me that would be optomised for a shorter draw length. I was over drawing because with my takedown,(with sights), I seemed to shoot tighter at the longer draw. He told me that bow was actually designed to be able to handle any draw length and the tips were in a bad position for my natural draw length. According to this study, the modern recurves gain in stability at their maximum designed draw length. I have been to shoots where the olympic archers were competing and when considering the arrow speed they were getting, it gave me the green mit envy blues. It is all about the specifics to get the best bow possible for the shooters parameters. Hunters can greatly benefit from the same tech. Imagine a properly designed bow for a particular shooter that can out shoot a bow that is ten or more pounds heavier, a huge advantage.
