    I'm with @Salamander_King , I believe it's the ratio of A/C load in EV mode (so it doesn't count in HV mode).

    Somewhat related: I did a small road trip over the weekend and got 5.x kWh/100km that;s 11-12 miles/kWh lol. How? because I was in HV mode and when I hit slow moving traffic through the construction zone, I switched to EV mode and just cruised at a steady pace (or stopped). When traffic started moving, I switched back to HV mode. This meant that the kWh/100km on the Eco Diary was only recording the steady state consumption and didn't include any acceleration (which would hurt those figures).

    I assume the same applies to the A/C Load Ratio value.

    Using the same trick but to the extreme, I was able to record 99.9 miles/kWh on one day. This is the upper limit for the miles/kWh display, so the actual number might have been even higher. LOL

    Agree! It really shows when you start out in EV on a really hot day and switch to HV after a couple miles like I did the other day. Had I been able to stay in EV after the cabin cooled and I hit the highway, the percentage would have been much lower.

    You can say almost anything with statistics. :D I did something similar once when it was new to me and I was experimenting.

    I got five good months of data showing the efficiency increase from winter to summer:

    I'm not as efficient as other drivers on this forum, but I'm definitely getting another 1 mi/kWh in the summer.
