Hi Many years ago while standing around (between races) with some pretty good stopwatches, a group of us decided to see just how well a set of people could time the same pair of start / stop events. Our conclusion was that as a group we could get agreement to +/- 1/5 second pretty consistently once we practiced a bit.
The obvious caveat: Since practice was involved, there could have been some “I’m clicking late, need to click sooner” feedback in the process.
