Will future Olympics have fierce debates over the length of artificial limbs?

Oscar Pistorius made quite the splash in the London Olympics by being the first person who had his legs amputated to compete in the track races.  Apparently, if one believes Mr. Pistorius, not all artificial limbs are the same.   Longer limbs apparently make one go faster. So how is the Olympics Committee to decide the proper length of the artificial limbs?  The longer they make them, the better the chance given to win the race.  How high should the Olympics committee make that probability?  From the UK Guardian:

"Don't focus on the disability," Oscar Pistorius told the world before these Games. "Focus on the ability." How right he was. There was no room for sentimental thoughts or emotional notions after the T44 200m final. 

It was not a procession or a coronation, but a race, raw and fast. And Pistorius came second. He was beaten to the line by Brazil's Alan Fonteles Cardoso Oliveira, who won in 21.45sec. Pistorius was .07sec behind him. He reacted furiously, telling the TV cameras in his post-race interview that "we aren't racing a fair race". 

Pistorius was convinced that the running blades Oliveira was using were too long, and called for the International Paralympic Committee to investigate. This from a man who has had to fight long and hard to overturn doubts about whether or not he himself has an unfair advantage when he is competing against non-disabled runners. . . .

One small reason that the speeds of Olympic Athletes might be increasing

I had no idea that they had put speakers behind the starting blocks for the runners.  But if this difference in sound can make the difference between who wins a race, it would appear that at least by that margin this change will make runners faster.  Should there be little asterisks next to newer times?  From The Atlantic:

When the Olympic runners take to their positions on the track later this week, they'll crouch on the ground, ears pricked, and wait for the starting beep. That's right, a beep. Not the pow of a gun, but an electronic tone, pumped through speakers, played by a "pistol" that's not a pistol at all, but something more akin to an electronic instrument with only one key. The pistol itself is silent.
The electronic "pistol" of this summer's Games was designed to overcome an astonishing problem: The speed of sound is too slow for Olympic athletes. That is to say, athletes far away from the starting pistol were delayed by the time it took for the sound to travel to them, and differences so tiny can matter in races in which the margins are so small. . . .

How to measure the US success in the Olympics?

Results as of earlier today

The best way to measure the success that a country has is in terms of Medals per Capita, not total medals.

Can you name the only American to win medals in five consecutive Olympics?

The answer is available here.  Hint: Despite the achievement, it won't be a name that comes readily to mind.
