LOL, I've seen guys with wingspans around 70", shove the bow arm out as far as possible, then draw back far enough to hook the string over their ear and then claim, "yep, 32" drawlength!".
I hear ya! I was noticing a pinching behind my right shoulder blade when shooting over 30 arrows a day. I tried going to a 28 inch draw from 29 and the pinch is gone. People don't realize that too much length and too much poundage can really hurt them. Everyone wants to be Superman and later on down the road wonders why they can't shoot anymore.
