Excuse me if I misunderstood your message above.Is that news to you? Tesla doesn't calculate the "added" kWh in the battery - they simply get the remaining range in miles/km from the start and the remaining range in miles/km at the end, diff is the "added miles/km" and then they multiply this number with the constant to extrapolate km/miles to kWh and show you "added kWh".
Are you saying that Tesla is taking the range number left at the end of the trip (lets say 10 miles) and uses the range number at the start of the trip/leg (lets say 150 miles), does a simple math 150-10 = 140 miles and compares this number with the 100% SOC number (lets say 273 miles for 60.2 kWh) and does another simple computation giving you the kWh your car get's ? This is pretty much stupid, if they do that.
It would mean that we don't pay kWh but "Tesla kWh".
My opinion is that the number we see as kWh added are the real ones, that get into the car, including the loses due to external and internal different factors that have an impact on it (temperature, etc.). The range number is not an indication of the real range of the car anyway, so why bother doing the whole thing above ? It would be idiotic, IMO.
