So if one part of my circle goes downhill, it has to go back up for me to arrive at my starting point. I finish exactly where I start. I have a gas station two blocks from the hiway on ramp, so the entire trip is all at speed. If I drove 45 miles down hill or with tail wind, then drove 45 miles uphill with headwind, and averaged, it would more or less workout the same. I am not so much looking for an example of daily driving as finding out what my provable upper number is, and by always running my test loop as close as I can each time, time of day, temp , etc, I can compare one set of results to another.

My concern is that your grille block is doing less for mileage in aero as it is in keeping the engine warm, and your A run gave your engine a nice warm setup, so when your B run was started, it was already at operating temperature and max efficiency- compared to two cold starts, one w/, one w/o, or ABA testing.
What you do and how you do is nothing for me to judge or criticize, I just wanted to know the scope of your test to get those results.
