Sure, but I don't agree that touch typing is "the" technique and that it's impossible that someone else has come up with a better one independently. Touch typing is a good way to type well, but I don't think it's distinct from "typing", it's one way to type. Just like you can play the guitar even if you don't know the technique.
> - Why do you think you did slow down after the switch to touch typing?
I have no idea, the way to hit the keys just feels less convenient to me. For example, the x and c are harder to hit because my fingers don't like going there, I can't really explain it better.
> - Why did you feel the need to switch to touch typing if the skill you already had was so good?
Half because I got an ortho split keyboard and couldn't use my old technique with it, and half because everyone said touch typing is so much better.
> - Do you regret switching to touch typing? Why?
Yes, my old technique is much more comfortable and faster. I still type the "old" way on regular keyboards, but it's not such a big deal either way, since I'm usually limited by the speed of my brain rather than my hands, and I don't much mind the reduced accuracy either. I'm touch typing this on the split keyboard right now.
> - How many years did it take you to get to 120 wpm at 98%?
I've been typing that way for 20 years, so I can't really say. I definitely remember being pretty good around 4 years in, possibly long before that.
> - Is there anything you miss from your old technique (beside the higher stats)?
It just feels more comfortable, when I touch-type I feel a bit like I'm fighting the keyboard, or as if I'm wearing shoes half a size too small. With my old technique (e.g. on my laptop) I feel at home.
