Stella Pajunas 1946 record of 216 wpm (54,000 strokes per hour, 900 per min, 15 per second, 66 ms) is on average. She must have typed considerably faster some of the time. Anything over 40 ms is probably noticeable.

Most wouldn't get near 1/3 of that but when the professionals say your shit doesn't work it does mean something. Trying to increase your speed using a system that cant keep up adds unacceptable annoyance.

I hereby coin the Pajunas rule at 40 ms.
