For me its not how fast I can type, my brain(ADHD or whatever this is) needs certain flow of speed; I think of something and want to type it, if I am delayed (e.g. imagine I change from qwerty to dvorak and am still learning) for whatever reason, e.g. key is stuck, my mind goes somewhere else, and then I have to "bring it back". Also as I am typing one thing I am thinking of another, or even third, so if something goes wrong with the mechanics of the first thing, then whole set of dominoes fall and I have to go back. Sometimes for a given thought I even type 3rd of 4th word instead of the first if for some reason my keys are not pressed. And then I type a word from the next thought and etc. It even gives me anxiety. As I am typing the code, I am thinking about the code that is going to use the it, and then the code one layer up, I also think of the machine itself, its wires, cache lines, or I think of how the variable I am typing now is related to its surroundings, I imagine a ladder to the moon each step with its address, and I think how far are things from "me", and so on. I cant speak of others, but for me keyboard layout and even key feeling/rythm is important just because it allows me to think uninterrupted.
