Photo finish uses a scan line moving faster than our eyes, yaar — it captures that exact thousandth of a second when the torso crosses the line. Hand times are always rounded up because the human reaction to start the clock adds a delay, so they add a cushion. But I’ve seen my own electronic time be slower than my coach’s hand-held stopwatch at a state trial, because his thumb was quick with love that day, and the machine felt no such urgency.
