I would question the accuracy of your speedometer & odometer (and thus
your mileage calculations). You're right that wind resistance (actually
it's drag) goes up as you go faster - dramatically. There's a
noticeable *decrease* in my mileage when I cruise at 70 MPH instead of
65 (which is why I'm now commuting w/ the Pimpin' Acclaim at 75-80,
instead of the truck at 70).
What's your GPS say your speed is?
