I don't do structured touch typing, I learned to read on a computer (early for my age, an old atari) and typing is more natural than writing. When I was in college, I used to do medical transcription and I peaked at about 120WPM with an acceptable error rate, I'd like to generate those diagrams myself... one thing is I'm much larger than average so one of my hands actually spans the keyboard, traditional touch typing rules just don't make much sense in my head.
