That's an assumption that needs to be verified. Sure, over a generation it's quite unlikely that evolution made for better mouse users. But we don't need to go that far. I mean, when you were testing during the development of the Mac, it was what, 1983? The mouse was a new thing, CUA didn't exist yet, I doubt that many vim and emacs users were part of the target group. I doubt that speed changes if you test the same demographic as back then, although it's harder to find people as unaccustomed to mice. In addition, has there ever been a test that includes mouse chords as used in Acme/Oberon?
