All my evidence is anecdotal (though confirmed with quantitative testing) but my sense of the "average user" is college friends of mine who do not program, and a broad selection of people seem to be able to hit 80-90WPM on the short tests. It used to be a that a "professional typist" was requested to hit 75WPM, and search engines still return that datum despite being a laughable number in the field now. I do not think any of my programming friends/colleagues type slower than 100WPM, and many can burst between 130-150WPM. Though based on your appellation of "super-gurus," there are definitely a few who fit that category, so selection bias could well be tugging my perceived average northwards.
