Sounds like good logic.IMO, long highway runs won't really change MPG results with hot country setting, its the stop and go that will hit the MPGs. I'd do it if I were you.
I think VW stock profile of compressor usage is dependent on RPM speed, at say 2K rpm at 70MPH, it takes an additional 5% of fuel to run the compressor, but at idle running that compressor running full tilt prob takes 50% more fuel, so VW tried to dial back the duty cycle of the compressor when the rpms are under a certain value to gain an MPG or so.
