Aerodynamic drag is a cubic function, whereas the increase in horsepower due
to increased air density would be linear. Is that too much of an
oversimplification DrMayf?? Therefore what we gain in horsepower we more
than lose in aero drag in the cool mornings, all other things being held
equal. This is why I believe that we tend to see slightly slower return
runs.
Just a thought
