They would need to know beforehand the precise span between the first and last athletes.
I think they did a pretty good job, it's only slightly stretched for an event when there was only 0,12 seconds between the first and the last runners, which is unusual.
- xanderlewis 2y agoI don’t see why the distance between athletes has anything to do with it; they record at a fixed speed which presumably is the estimated speed of the winner crossing the line. So it’s known in advance, and the stretch factor if they get that speed exactly right is 1 anyway. And of course when I say ‘speed’, I mean [width of strip] / [time between the capture of each strip].
