WTF does Max A/C do?

It doesn't say "windows down" (nor did I say that).

I don't know if it's right or not (and I honestly don't care )

If your objective is to "push" hot air out the window, you'd be better served by using the Normal setting, since it pressurizes the cabin because it's drawing in outside air. On the Max setting your cabin air isn't pressurized, therefore you're not pushing as much air out the window as you could with Normal.
