I type fairly quickly, and of course my job requires this. I find that these typing tests, though, are inconsistent and the fact that you have to read what you are typing as you type it is not a good approximation of how you type when you're typing what's in your head anyway. At least, that's the case for me.
Not very fast, unfortunately. Never took typing in school, and never needed the skill on the job at all until we converted over to CADD computer drafting. After several years of having to do typing on my design drawings I still consider myself a *hunt-'n-peck* typer. I doubt I could do 40 wpm without several mistakes.:frown:
I know that in a situation where I'm reading from something and needing to retype it, or where I don't have to think about what I'm typing, I can average between 130 and 160 words-per-minute with 97% accuracy (and I even have a typing certificate around that I needed to get for a previous job that can prove it!). When I'm typing from my head and typing leisurely, I'll usually average around 110 to 120.
As a slightly humorous anecdote, I took a test for a job a few years back and effectively typed *faster* than the typing test could follow -- I maxed the machine out at 99 WPM.
I don't really think typing speed really matters. Not only that, but mistakes happen; would you rather misspell a word, or spend 0.6 precious seconds backspacing? If it's under 50 wpm then you may have issues with getting your point across in a timely manner against a skilled typer, but honestly, once you get up past 100, it's more important what you say than how much you say.
