key chatter is a legit problem, but that doesn’t mean a key gets pressed 25 times per second.
key chatter can occur up to 4 times at max. Even the keyboard firmware will not allow it because it is technically known as debouncing which is coded by the manufacturer to eliminate it. So even with the debouncing algorithm there might be some key chatter which is as i said can be within 2-4 times per second.
My 2 cents as an Electrical Engineer.
