I'm 6'4", so I'm very aware of my reclining rate, but from my experience shorter people usually recline faster, maybe not aware that people's knees are that close to the back of their seat, due to the fact that their own knees are comfortably away from the seat in front of them.....Only expection to that rule I've seen is when there is a larger person (height + weight), and it seems that they aren't able to control the rate of recline, due to their own mass.
