This is pretty accurate. I think my casual speed is around 80 wpm, my overdrive speed is 100+, but I clocked in at the school typing test in 9th grade at 126wpm.
Keep in mind my fingers are pretty clumsy and I think the backspace is the most used key on my keyboard. I have to backtrack often. I'm pretty sure most of the actual errors that I submitted during the test were things like, how many linebreaks do I add after a paragraph, and the awkward break in the middle of the double dash "--".
