> Note that, unlike the other measurement I was able to find online, this measurement was from the start of the keypress instead of the switch activation. This is because, as a human, you don't activate the switch, you press the key. A measurement that starts from switch activiation time misses this large component to latency. If, for example, you're playing a game and you switch from moving forward to moving backwards when you see something happen, you have pay the cost of the key movement, which is different for different keyboards. A common response to this is that "real" gamers will preload keys so that they don't have to pay the key travel cost, but if you go around with a high speed camera and look at how people actually use their keyboards, the fraction of keypresses that are significantly preloaded is basically zero even when you look at gamers.
