I think that I type similar to the way that you do.<p>I don't make my individual fingers move, instead I arrange my fingers into different patterns (repositioning my hands if needed) and then kind of execute the key sequence. It is weird and I don't really think about it but my fingers never return to the 'home keys'. (Normally they are already on the next key that they need to be on). (If i'm typing 'ere' my  left-middle will stay on 'e', if i'm typing 'different' my left-middle will be on 'e' and left index will be on 'f' before i'm done typing 'i').<p>I think it has to do with being able to think a few of symbols ahead, as you would with music.<p>I'm probably &#62; 90 wpm, as well, and no RSI.
