The practical exercise in the most recent CPD video from the ACO on run-outs was a very good one. I didn’t know about the flash-lag effect, but I got 16 out of 18 correct anyway, with one wrong in either direction. There was one more where I thought the batsman was probably out but I wasn’t certain, so gave not out – correctly. My positional judgement varied around the actual frame the batsman was in by a frame or two either way, with about a third of my correct decisions being spot on.
I think that’s a pretty good result, but I shall revisit the exercise in a couple of weeks to make sure it wasn’t a fluke.
I hope they do one on LBWs soon, that’s the area of umpiring that I struggle the most with.
