However, professional typists type a lot faster on average -- upwards of 65 to 75 WPM. A good typing speed compared to the general population would be over 40 WPM, but compared to professionals it would be in the 75 WPM range.
Comparison of typing speeds, like most other things, is very subjective. A typing speed of 84 wpm is certainly much higher than that of an average person. I'd say that most people who haven't learnt touch typing would key in under 60 wpm. If you're comparing yourself to such people, than yes, 84 wpm is really high. However people who do learn touch typing in can key in much faster.
