Good point of reference, thanks!
But I still view this as every scout there did their own hand-timed numbers ... and I think the human lag still applies. See, the human starts the timer as a reaction to a sound, so there is a physical lag. But when the player is nearing the end of the run the human anticipates that ending and hits that end timer pretty much on time. That average lag is about one tenth of a second ... no matter what the official hand-timed number ends up being. If you want to do that realistically, videotape it, turn off the video, and have a sound that happens when the player crosses the finish line. Then have a player time the sounds, without the video ... and you will have normalized for the human lag a lot more than live human timing.
