One of my trips yesterday wound up mis-reported. The mileage and driving score were correct, but the brake score, the EV miles, and regen miles were reported as zero, with that causing (I suppose) the trip to be reported as 0% EV and the MPGe to be reported as 39...
Oddly enough, the battery image appears to be correct (it matches the image for the equivalent return trip), even though it says 0.0kWh next to it.
The trip itself was unremarkable, although I did plug into a new-to-me charger at the end of it; that charge is listed correctly.
Does this happen often? I don't really care all that much, I'm to new at this to be anywhere in the rankings, so it's impossible to be competitive in that arena, but I find the information interesting.
