But the question is... so what?
Look, It's obvious I don't give much credit to touch-typing. That much you realized by now. And that's my only point.
I think I type at 70 or 80 WPM with a accuracy rate on the 90%s mark. Just did a few tests after googling for it and the lowest I got was 50 WPM on a rather difficult test with lots of punctuation. So I take this 50WPM as my probable typing speed while coding, where the 70-80 WPM as my probable speed on a text processor or on those days I'm feeling particularly skillful (or when typing in Portuguese).
The thing worth mentioned is that not even once someone complained to me I type slow (quite on the contrary!), nor as any project where I have been involved been delayed over an hypothetical slow typing. If you look at me typing at 70-80 WPM, you will most probably not be able to tell much of a difference from someone typing at 100 WPM. 20 or 30 WPMs amount at best to 1 more word every 2 seconds. Hardly something you can spot unless you time it. Neither it will have much importance on modern IDEs and programming practices.
Meanwhile, no RSI here or carpal tunnel, diabetes, crabs or or other niceties. Just an addiction to coffee and smokes and enough success on my career to make me proud and financially secure.
