I have not found typing speed to correlate well with productivity. I spend quite a lot of time thinking while coding.
I once worked (mostly remotely) with a guy who I'm pretty sure couldn't touch type. He wrote pretty dense code and used very abbreviated class/variable/method names. But the real clue came from communicating with him via slack. It often felt like talking to someone much less intelligent than I knew him to be. His messages were so terse that I was constantly having to make a lot of guesses about what he was trying to say. Needless to say, it was not a great working relationship.
Of course it doesn’t help at all if you have a long build or deploy process before you can see the outcome of your changes.
