I look at that and think: the only time my unmodified 1998 DX got 44 mpg was without AC and at 55 mph and with me alone in the car. You drove 80mph with the AC on and got 44mpg. Looks pretty good really.

Yes, but he pays higher insurance premiums, possibly car loan interest, higher auto taxes if your state has them, and he faces several thousand a year in vehicle value depreciation costs. You do not face those costs at nearly the level he does.
Pretty good really.
BTW, I still don't believe my own calibration, but different instruments keep showing me the same results, so I obey the best known facts.
