Hello -

Maybe you could apply a set of theoretical "trips". Imagine a track with hills and valleys, stoplights, and traffic jams.

One thing I did notice is that the calculator does not take into account what gear you are in. However, that is already discussed in the thread that is dedicated to the calculator :

In terms of correction factor, it must be a range based on context. Urban vs rural, snowy winters vs mild winters, windy regions vs calm regions, etc ...

I look at the calculator as the "MPG Limit" of my vehicle. I think that it does allow you to do a "what if I lower my Cd by X amount" and see what happens to your MPG.
