Here are two changes that I would like to see discussed:

- timing method (hand-clocked times apparently were a tiny bit faster)

- elasticity of the running surface (if you wonder why they added lanes to the track but kept six sprinters in each race: you go faster on an inelastic surface, but running on it is less comfortable, to the extent that doing a 5k run is too painful. So, the innermost lane is softer)

Timing and timing source accuracy was the first place my mind went to after seeing the animation. I believe that when I ran cross-country and track, decades ago, that the timings were tracked by hand, even at regional and state competitions (in my experience and to my knowledge).
