In my opinion having read a lot about it now and studied the image I posted a lot, only a right handed person would be faster using DVORAK. A left hander would probably be faster using QWERTY because QWERTY makes the left hand do over 50% of the typing. Being left handed this makes me naturally faster than you Right handers, and btw, I use my mouse right handed so QWERTY for me is truly a natural way of typing.
