After I switched to Dvorak and achieving 80WPM, I switched back and my QWERTY had gone from 80WPM to 100WPM. The point was that with life-long auto-didact QWERTY skills, I don't use all my fingers, and my dominant hand actually covers slightly more area. Learning Dvorak from scratch bought me some discipline. Takeaway: Besides playing speed typing games, perhaps learn a new layout simply for the dexterity exercise.
