I did not deliberately shorten my draw, but I did shatter my left collar bone and when it finally got to the point where it was "healed", the bone had overlapped itself and was half an inch shorter. That made my draw length half an inch less.
It sounds to me like you have adopted a better shooting stance. Don't worry about the speed or efficiency of the longer draw. At 29" you still have a longer draw than most people, and if you think it is more comfortable, then you will almost certainly shoot better. That will translate into more success on targets and game.
