I think I'm coming around to agreeing. I'm not counting the Bonanza TC tip tanks because there was a known issue and I don't remember if the fix is out, but the fuel state saving is not working at the very least.
I believe weights are since I always load with only the pilot and no copilot weight, and the tablet settings and avionics are correct, but now I wonder if my engine is always at 100% because of my devilishly good flying or because it's not saving any damage I'm incurring.
