For the last 4yrs I've been charging to 60% SOC, but usually because of my fat fingers, it's 58%. I drive around 30miles, so when I get home it's 50%. Then I can toggle the meter and see whether 50% is 155miles, to know if there's any degradation. My 2018 started with 310 EPA-rated miles. It still has 310 EPA-rated miles.
As you can see, I did the calculation from the Consumption chart and it calculates 75.6kWh. Of course, there's quite a bit of rounding going on. SMT is showing 76.4kWh.
My SOC is about 6% when I got home, last Friday, because I had just gone skiing, and driven 170miles, which is pretty good for starting with just 60% SOC.
I put a line on the first chart showing that I had just gotten a software update, and it fixed the Consumption error that has been going on for a while. My consumption figures are back to normal, where before, you could see how much higher the consumption was, when it was in fact, wrong.
