tested the keyboard polling rate and found 1000hz. How is this possible?

I pressed any key, but the shortest key press was 1 ms.

My keyboard is RAZOR Blackwidow linear and I use the Razor yellow switch.
There is no debounce time on my keyboard, and the scan time is 1000hz and the polling rate is 1000hz?

I thought all mechanical keyboards had 5ms of debounce time, is this a lie?

as I envy you, my keyboard software does not work even after I set 1000hz. 22ms.....
