Did manage to mess up 2 words, 1 when my "p" key (Fell off, now superglued back on, not always 100% responsive) didn't type, and I didn't realise, second when I misread "cold" as "could"
Anyway, I found that pretty easy, and I think if I really pushed myself I could get up to around 110WPM, I'll try tommorow xD
EDIT: Did a second one, wasn't happy with first, still think I could be faster though.
