How would you like to lose the gold by one-thousandth of a second? merican Tim McKee had the misfortune to swim for AOlympic gold just as a quantum leap in Olympic timing technology overshot the bounds of common sense. When McKee competed in the 400-meter individual medley in Munich in 1972, Olympic swimming had just converted from stopwatches to the use of electronic touchpads. Official times were still sliced no finer than a hundredth of a second, but the touchpads could differentiate a winner to the thousandth of a second. McKee tied for first place with Gunnar Larsson of Sweden to the hundredth of a second, but lost by two thousandths of a second. A time so fine, it turned out, that it could have been affected by a coat of paint, given disparities of Olympics in 1984-they were both Georgetown University.

"We did a new system last year to make an automatic recall on false starts," says Gibbons, "but the rules in track and field say the only person who has the right to recall is the starter.
