I was using the speed test part of a typing program earlier, over and over, trying to break 150 WPM. Best I could do was 147 (146 adjusted for IIRC a 2% error rate) a few times.
But when I’m not making any effort to type fast, I type at around 100-120. But after prolonged fast typing (maybe for a half hour) I got a nasty headache that lasted around 2 or 3 hours. Just wondering if this happens to anyone else.
