Summary - powercranks are very spendy, their usefulness is debatable, spend your money on zipps.
It was actually very simple. All he had to do was get some results at upcoming races that matched his claims. Questionable numbers (which we see here from time to time) should be accompanied by results otherwise they will remain questionable numbers.
Or as others have put it, "extraordinary claims require extraordinary proof."
Lastly, the Powercranks inventor is well known for making ridiculous marketing claims. He always claims that Lance, whoever wins Ironman Hawaii, etc., is secretly using his product.
