I took the course, use all my fingers properly, and am still impressed with myself when I manage around 70 wpm. Thing is, that's with about 98% accuracy - and that has a lot of value. I knew a woman who typed 120 wpm, but her accuracy was about 30%, so the edits and rework were maddening and took far longer than if she'd just typed about 20 wpm in the first place.
