Milorad Cavic: "I did touch the wall first" in Beijing

Movies are shot at 24 frames per second and look continuous to the human eye, thus we know the eye can't discern a difference of 1/24 = 0.04 seconds. I'd say anything under 0.1 seconds looks pretty much simultaneous to the human eye. The USS Swimming standard for backup timing cameras is a minimum 100 frames per second. I'm not sure what the olympics used. 102.16.2.B.(1) Back-up timing cameras recording a minimum of 100 images per second. The cameras must be fully integrated with the timing system.
