That's an excellent thought , and to be honest I know the software shows it , but I really don't see it. I am in fact always conscious of it , but I never pay attention until it's finished because it changes so much within a few key strokes.

It seems to me that my left forearm is getting tired with touch typing. I don't know if that's form or just unused muscles since I'm using my ring finger and pinky so much more now.
My right arm is fine, but then I like the reverse monkey grip so it's gotten extra work on that side.
