As menctioned, pro-gamers train combos for hours daily. The best of them can press up to 10 keys per second without thinking. For example, the fastest StarCraft II player Reynor (Riccardo Romitti) can sustain 500 key presses per minute, and do short busts of 800. He has videos explaining how to tweak the Windows registry to achieve such rate (it involves pressing some keys once and the OS autorepeats faster than you can press), because it can't be done with the standard config dialogs. And you are trying to tell me that you can do double that... not only double that, "much faster" than that.
I dare anyone to make a script that, after launching, will ask you to press Ctrl+C after a random wait between 1000 and 3000 ms. And record your reaction time meassured after key release. It's allowed to "cheat" and have your fingers ready over the two keys. Unless you jump start and get lucky, you won't get better than 150ms.
You don't make a typo, press enter and then start reacting to the typo.
You start reacting to the typo as you're typing. You just won't get to the end of your reaction before you've pressed enter.
The point of my combo comment is that pressing Ctrl + C is not the same thing as typing two random letters of a random word.
Combine these two things and I think it's possible for somebody to interrupt a command going out. The question is whether you can press Ctrl+C while typing faster than 100ms, not whether you can react to it within 100ms.
Also, people regularly type faster than the speed that pro StarCraft players play at. The sc2 players need the regedit because they will need to press Z 50 times in a row to make 100 zerglings as fast as possible, but you don't need that to type.
for single mouse click, 225ms is pretty typical for me after a bit of warmup. sub 200 is not consistently reproducible. i dont think i've ever cracked < ~185ms
