1) I've been getting 13.9 over the lifetime of the car (admittedly it only has a few thousand km on it now). Charging losses are nowhere near 15%, perhaps 5-6%;
You need a wall outlet energy meter, it seems to me, or you're never going to get it.
I do get it. I post facts, you read what you want.
And, I've many many times said I realize there are charging losses, however, those are probably similar (or less than) the difference between the EPA/DOT figures for fuel economy for ICE cars I've been quoting here, and their real world numbers.
Oh, and I do have a wall outlet energy meter, my charger tells me exactly how much.
I've "filled" my car up today, I'll run the next 150km or so, and then fill again and compare the in-car usage with the distance/kWh required to top it back up. I'm guessing well under 10% difference.
You need to stop jumping to conclusions, and instead look at the real world numbers that the owners of BEV / PHEV vehicles are posting here
