I'll throw in too... I'm 6'0", and draw 31". I measure quite regularly, and carry a bare shift with a zip tie around it (to mark the length when I draw) in my back quiver. I was taught from the beginning to fully expand when drawing, and not hunch. My dad was 5'9" and drew 29", my brother is 6'2" and draws 32.5". Maybe we just have long arms, but I also think it has a lot to do with technique. When my draw shortens up, is because I'm collapsing before release, and I have to watch out for that.
