Unfortunately this falls apart when I try to type anything that isn’t common English words: names, code, rare words, etc.
I also think that the keyboard could learn the different “rhythms” of typing - my normal typing which is fast and practically blind, and the careful hunt and peck which is much slower and intended for those out-of-distribution inputs. I bet the profile of the touch contacts (e.g. contact area and shape of the touches) for those two modes looks different too.
So I realized I had exchanged correcting the same word four times in a row to correcting the same letter four times in a row.
