Not touch-typing

I have avoided split keyboards because I rather like my qwerty typing as it is so, last time a split keyboard was required of me, I used a Programmer Dvorak layout at work, and continued with my odd qwerty typing at home. Among other things, I have been somewhat aware that my choice of finger is not independent of the other letters I type, that my fingers are trying to find paths that will keep them out of each other's way while leaving the next letter near the position some finger is in already. For example, the is a one-handed word with my middle three fingers, my little finger can handle shift for the initial capital if need be. Recently, I discovered a specific example of the inconsistency: when I type depending, I use my right index finger for the first n and my second index finger for the second n. However I type is probably consistent over whole words, just not in mapping of finger to key.
