There is no expectation of a character appearing on screen until the click. So the latency between key touch and click has no feel of latency to a person. The flip side is that there is no expectation of a character appearing until the click happens. So a keyboard with a click which reduced latency by a lot would start showing characters before the click occurred -- and this would be incorrect behavior. If I'm touch typing on a keyboard with full travel distance, I may have more than one key in motion at the same time, so the latency of each keypress doesn't exactly add. Additionally, if you're talking gaming keyboards as article goes into, you don't time your "shot" for when you first touch the key. The timing of the shot is relative to when the click happens. You might even milk the key the same way you milk a trigger on a gun. Or if you're in a rapid fire use you flutter back and forth across the threshold with a clickless switch like cherry reds, and you don't use the full travel of the key. Either of these the latency measure in the article doesn't line up with real world use.
