Sprinting: let's slow down a bit

All credit to Asafa Powell for becoming the fastest man over 100m. But when it was only by a hundredth of a second - and the fastest thousand men on earth are separated by just a second - aren't things getting a bit ridiculous?
After all, the slightest breeze, the smallest bump, and the fastest man is back down to number 50 or so. The top 100 world rankings are down to nothing more than luck - and often that luck involves not getting caught with a syringe in your arm. When they're all so closely spaced, what's the point of awarding a gold medal to the one who happened to be a hairsbreadth ahead at the tape? Surely it's not worth millions a year so one human cheetah can stand on a podium - especially when your nation lacks schools, hospitals, and hope.
I call it the One Percent Principle: once you get into the top one percent of anything, the extra rewards of climbing even higher are negated by the time and effort it takes to get there. And if you make it, you'll have worked so hard you won't find it fun any more, and it's only a matter of time before someone takes it away.
