That's my current typing speed record after just over 1 day (cold turkey), a net typing time of about 5 hours on Colemak. I am coming from 65-70 WPM on Dvorak after 6 months. My Dvorak speed hadn't increased for 4 months, and was still just below my QWERTY speed.
Note: I am keeping Caps Lock, but moved delete to return and return to tilde. I just now changed it, so I'm still getting used to it, resulting in a lot of accidental deletings.
Okay I'm not sure if that link works, but I got 18 WPM.
