It doesn't happen often, but I'm stumped. As far as I know, the meters measure your output in watts. Not sure how aerodynamics fit in.

I think they're referring to the resistance in a wind tunnel and it being comparable to the other doodad.

Seems to me that the power meter would measure output, while the wind tunnel can possibly help determine the most effective use (position on bike) for that output.

Or not.
