I'd never really taken that many typing tests before. I tend to get distracted partway through them and can never type at a consistent. However, I really wanted to try the "advanced typing test" on 10fastfingers, and thus I needed to do ten of them. I decided it would be a good way to analyze some of my keyboards and how they perform in more depth. What I found out was what I already knew, that I prefer heavier switches. But, I found out why in a bit more detail.
The best performance came from my model M, and my MX green and white boards, which all performed about the same, hovering around 80 WPM.
My black alps board came in around 75 or so the few times I used it, and my board with clears was around 70.
My HHKB, however, performed dreadfully. The 3 times I used it I got 55, 63, and 50 WPM.
As I said, clearly I performed better with heavier switches. But, upon further analysis, I managed to figure out why. When lifting my fingers off of my HHKB's keys, the springs wouldn't really push my fingers up as much. Therefore, I'd hit the sides of other keys much, much more often. This would give me accidental presses and/or slow my fingers down. Looking back on it, I had this same problem with blues, only much worse than with topres. It's a shame that the force curve for most switches offers less resistance on the upstroke than the down stroke, otherwise life would be much easier for me.
Anyways, do you guys prefer lighter or heavier switches? For what reasons? And has anyone else run into this same problem? I'm curious as to wheter there may a difference in typing style or something between users of each kind of switch, leading different switches causing different problems.
