What is involved with using a power meter for aerodynamic drag testing? I've read about pro riders sometimes doing this during the season (presumably because they don't have time to travel to a wind tunnel). How accurate can a power meter be vs actual wind tunnel testing?

Right, the power meter would measure power output so I suppose what you'd get is a relative improvement not an actual reading of your drag. I was just wondering if I ride around a track at 25 mph and test different positions is that going to tell me anything, or are there too many variables?
