I'm not very knowledgeable about this stuff, but since it was my 3 year ownership anniversary this week, I decided to get the Leaf Spy (lite version only) so I could put out some info about my car/area. For those not familiar with WA state, Pasco is in the hottest, driest part and routinely gets temps above 100 F and often above 110 F. This summer has been a bit hotter and longer than usual, but I'll have to wait until it's over to know for sure.

Hx - 67.29%
Parked in sun - 3 days/week (this one is tough since I normally bicycle through the summer and the car sits in an uninsulated garage. However, I still drive it for errands and get lazy at times. I also park outside at night in the summer to help cool the battery as much as possible. I also keep the battery between 40-60% SOC most of the time. However, now that I have LeafSpy, it appears that the outside cooling doesn't really help much, and the %SOC is higher than it would appear from just the number of battery bars)
I have no idea how this might help the Battery Aging Model since any close city (Seattle/Portland/Spokane) has a completely different thermal environment. If I were to guess, maybe I'm closer to Sacramento.
