I found that my finger placement on QWERTY keyboard is a bit different from the map shown here https://colemak.com/Learn . I've been taught to place hands symmetrically, so the left index finger is used for keys GTC - DV - B (colemak scheme). Probably this key-finger binding will change the statistic available here https://colemak.com/Compare . I tried to print according to the colemak fingering scheme and found it difficult and clearly unnatural to my left hand. Then I discovered that dvorak fingering map assume the same hand position. In my opinion, in targeting problems related to accuracy / speed / RSI, the fingers' placement scheme is nearly as important as the keyboard layout itself.
