Are online reaction times accurate?

Is 200ms a good reaction time?

The hard limit for human reaction speed is around 200ms in an empty situation. If you’re looking for a specific thing, you are very well-conditioned, but it could happen at any time, so you’re going to react to it around 200ms or slower on the average. Now, 200ms is superhumanly fast.
