I picked 30ms from here: https://danluu.com/keyboard-latency/ https://danluu.com/keyboard-latency/ It seemed a reasonable number for a goodish keyboard on that

  The methodology of that test was a finger pressing the key and includes that travel time. So it's hard to say how much latency comes from the keyboard vs. the tester's finger speed & consistency. An interesting set of numbers, but doesn't tell you all that much about the hardware quality itself. The actuation point and travel distance of mechanical switches is itself an endless source of user opinions & discussions.
