I think your relative efficiency increase will remain close to 4% regardless of ambient temperature.
Phil can correct me if I'm wrong, but when he said his cold weather aero enhancements didn't really "show up" at the pump until the return of good weather, I believe he was referring to his "previous best" (warm weather) MPG performance, not strictly a before/after comparison in cold conditions.
All else being equal, your
absolute MPG will also be higher when the warmer weather returns, but the relative improvement of aerocap vs. open bed should be about the same (at the same testing speed).
