If you still haven't tried to take a test for it,here's a site:
http://www.mtworld.com/keyboard/



I got an gross of 45 words per minute,with 27 spelling errors and 7 punctuation errors(which is a lot,but wasn't much focused either).I did the three minute test as duration,and the topic was Laryngoscopy Surgical Report.I think my speed is ok,though,I will take some other tests with higher concentration to see if I can reduce those spelling errors.

So What's your typing speed?

I did the same test as you.
Was a rather hard text.
Got 42 wpm and 8 errors.

There I got an average of 55 WPM.

I started using a different keyboard layout three months ago so I am still not as fast as I used to be.
http://en.wikipedia.org/wiki/Keyboard_layout#Neo
I type with 10 fingers.

That text is arguably the hardest there,but still impressive score ;p.
Also,Redundant tried this site http://speedtest.10-fast-fingers.com/ several times,and my scores will almost similar to yours(sometimes my computer lags on words,lel).Still,I love the ranking feature they have on that site.
I feel that I'm fast at typing(moving my fingers and fast knowledge of place of each letters),but I'm not consistent enough,and have lapses of concentration.
