>Nobody measures keyboard latency this way (keypress travel)
You'll find most keyboards in your link, despite these fullrate-enabled high poll rates, actually have higher latency from keypress to event than what PS2 trivially achieved.
Which, by the way, is consistent with the findings in Danluu's article ("a joke"), showing that pressing 2 keys at once might not be as accurate, but does not completely compromise the results, relative to using a mechanical arm.
Note that Danluu documents his methodology, and even expresses that he would prefer a mechanical arm setup.

Is undeservedly unkind.
