From the article:

Pistorius's paralympic world record of 46.34 seconds is however way behind the best times by able-bodied runners.

The fastest time of an athlete still competing is 43.50 set by American Jeremy Wariner, while the world record stands at 43.18, set by compatriot Michael Johnson. Pistorius has also not managed to achieve the Olympic qualifying time.

Seems to be they are putting the cart before the horse...and not a bionic horse, either!
