I think There should be a feature that tracks your fastest and slowest words.

Keyhero should track how fast you type each word on average in characters per minute, and keep a table that lists every word you type in order of fastest to slowest. It would be interesting to look at. Words like "the" would be probably double your usual typing speed, while longer words would be near the bottom of the table.
