  1. Blocks, then the upright run

    Florence Griffith-Joyner's 10.49 at Indianapolis on July 16, 1988 includes the reaction and the drive out of the blocks as well as the meters at top speed. On a race this short the start is a large piece of the clock. The all-time list keeps the legal personal best. A radar on one stride would read higher than the race average, and it is not the race.

  2. 21.3 mph is the average

    100 meters in 10.49 seconds is about 21.3 mph from gun to finish, not the speed at 60 meters. Florence Griffith-Joyner ran that average at Indianapolis on July 16, 1988. Hundredths of a second at this distance are a few centimeters at the line. They are not a different event.
