I think I'm above 50wpm because I can type very fast and I know the keys. I have proven this to my buddies as they read me a paragraph and I typed it without looking down at all. Only had one error!
I used to be really fast on a Pearl with Suretype, and didn't need to look at the keyboard. Now on the Curve, I'm definitely much slower. Maybe there's some standardized test or paragraph we could agree to do and time ourselves by, that makes use of most of the keys on the keyboard. Sounds like a fun thing to do.
