Hi OE... I'd think being in SF you would never have to turn on the A/C and only use the fan only (with display showing AC OFF)! Now if you go outside the city to San Jose or anywhere East of Oakland, then yeah you may have to use the A/C. But I wouldn't just leave it on Auto when you can blow cool air in using just the fan. This would also save your SoC as well. I notice when the family is in the car and they have to have A/C, my SoC is used up about 10 times faster than just being alone in the car using only the fan.
Aside from the A/C, for the car not to AS very often, your mileage seems very good (51.1 based on your sig).
I get so frustrated if I ease on the brake coming to a red light, have the AS engage when I drop below 7mph, then as I coast to the line I press the brake to stop completely... BUT misstep on the brake (or start to go slightly backwards) and the ICE starts back up again. At this point it will never go back into autostop while I'm sitting at the light

. If I know it will be a long light (more than a minute or two), I drop it in park and turn off the engine. I'd rather do this than watch my mpg drop while sitting there with the ICE running!
I often force the car to NOT go into AS (by shifting to S) when coming up to a stop sign or when I know I'm coasting up behind someone, the light turns green but I will end up going below 7mph (but not stop completely or not be stopped for more than 10 seconds) before the car in front starts moving.
