This thread needs to be moved to its own topic. Anyway, I had the chance to test the 'Alozzy scenario' this evening. It's a cold (mid thirties F), rainy night with very high humidity, so I ran heat and A/C at the same time, while watching the energy monitor for all systems (which, BTW, is accessible only from the infotainment screen menu, for some reason).
They screwed up the climate control display, and it does indeed show a big drop in energy usage when the A/C and Heat are on together. This can't be possible for the reasons I listed above, so some Nissan firmware programmer goofed. I suspect that when both modes are engaged, the energy monitor stops 'seeing' the drain for the PTC. It was showing less than 500 watts total draw for climate control, and that likely isn't possible for resistance heat alone, much less for resistance heat and A/C.
