Approximate finger use frequency while typing

I worked this out for a story I wrote today and thought I’d share. Assumes a qwerty keyboard, does not count spaces, numbers, punctuation, etc.

Finger, percent of all presses
Left pinky 8%
Left ring 9%
Left middle 20%
Left index 22%
Right index 20%
Right middle 8%
Right ring 12%
Right pinky 2%
