It is difficult to unlearn once you learn it incorrectly. I have learned to touchtype about 80WPM in my teens, over 2 decades ago and I still have hard time not bottoming out or using right shift key. I have been successful in re-learning to use dvorak instead of qwerty and to type in a tempo (ie. with equal intervals, using metronome), but the bottoming dynamic is much more basic than that, I think.
