Same for me, ish; I often find myself just using backspace and retyping the last few words if I find a typo a few words back, as opposed to reaching for the mouse and redoing just that word, or using the keys to go back. Going four words back is usually a matter of alt + left-left-left, alt-backspace, re-type, but still I find myself just deleting the last couple words and retyping it.
How do you learn "The Robot"?
I especially do this with my index fingers who will often jump from, say, Y to U directly without hitting J in between. It looks very funny because they often hover above the keyboard because of this.
But I do tend to move my wrists too much when typing.
Oh. I don't know how common it is, but I just tried typing "yuuuuvawere" and noticed my fingers don't come back to home row unless I am done typing. They do sort of hover over it but there is no j between y and u. May be I am wrong, but touch typing doesn't teach to bring back the fingers to the home row after every letter. I learnt touch typing with some typing software which taught single letters, commonly occurring n-grams for n in (1, 3), commonly occurring words etc. So it might be my muscle memory that tells me that there is no need to go back to j if you are typing "you".
If my pinky is at "shift", I don't feel the need to bring it back to 'a' unless I have to use it directly or indirectly. Same goes for other fingers.
But the 110wpm rate is worth it. And people look funny when I blast away at the keyboard without a screen in sight (I often type on a bluetooth keyboard attached to either ipad or iphone)
edit: The funniest result of being a quick typist is that I use copy+paste less than I did a few years ago. Often the context switch between typing and selecting is too much work and it's quicker to just type things twice.
