Lets work on a lava burst macro!

Sorry to say this, but you are way misinformed.
I easily spam a key 6-10 times a second, and some friends of mine have been up to 20 in some situations.

Sounds like a couple of times to me. Notice that I didn't say "the average tapping rate of a healthy teenager is 5 Hz" or something similar - I left it vague because I didn't feel it was essential to the point. But if you want to get all precise and sciencey...

If you need it to be that precise, it's not that hard to design a test get a more specific answer, or there are several good ones in use. Don't forget to take several trials to get better data. Here's some data from a research study by Cousins, Corrow, Finn, and Salamone in 1997. These are from 10-second trials, so 55 total taps is only 5.5 Hz (5.5 taps per second).



Let me know what method you and your friends are using to obtain and calculate almost four times the maximum rate this study observed. A 20Hz repeated keypress rate seems rather impressive, even allowing for potential differences in stroke length and so forth introduced by choice of testing methodology.
