I must be missing the flaw. They use goofy, kind of bass akwards descriptions, but say the same thing. Faster rider gains more speed, slower rider gains more time.

Personally, I think it is silly for a slower rider to use this logic to buy aero improvements, but that doesn't mean marketing won't try to sell them that way. It is far easier to gain 30 watts from 150 to 180 through training than it is to gain those same 30 watts from 350 to 380.
