A hint at what wpm I just typed at would be nice. So if I only hit 50 wpm a 50 off to the side or below the dotted line.
This is fascinating when picking a liminal wpm. Single hand words are so much harder.
I can cruise along until I hit words like "exact"
EDIT: You could make a list of bigrams as people type and average the wpm for words with that bigram, then you could weight the randomly chosen words by the difficulty of the bigrams, to really help people focus on their biggest stumbling blocks.
