Climate controlled cars like mine work on the same principles except the computer controls the mixtures. None of this should have anything to do with the compressor cycling. Turn on your a/c in 30deg F weather and see what I mean. It still turns on and cycles regardless.

The only thing I could see the tint doing is making it stay cooler longer if you wish to manually switch the a/c on and off every 5 minutes or making it cooler in general so you dont need a/c

If I am incorrect as to the operation of automotive A/C please correct me.

This was true in older A/C units, but newer ones cycle on and off depending on inside temperature. My Peugeot has something called Klimatronic, you can independantly set a different temp for the driver and passenger, and when driving I can feel the load suddenly increase when the compressor turns on.
