250m 22.9-23.6
300m 29.3-29.7
500m 54.5-55.1

tommie smith
250m 23.4-24.0
300m 29.7-29.9

ben johnson
60m 6.22-.28
100m 9.50-.70

Anything is possible depending on who is using the stopwatch! Remember, Donovan ran 14.99 in that 150m race where he beat MJ. 14.99 is a far cry from 12.99.

No way MJ or anyone ran a 150 in 12.99, that is unreal.

if you start the stopwatch after a third of the distance is covered anything is possible, 12.99 is just the starting point.
