Carwings reported my last mileage efficiency as 6.7 miles/kWh.
And that is why people are reporting the value from the car or the wall/Blink, because Carwings' data is not accurate.
If you get the NTB11-041 Carwings update, you may find CW is now (close to) accurate. I think my car's screen history, rather than the dash, may be the most accurate report of m/kWh. See this thread:

CW is now under-reporting my distance traveled, as compared with both my odometer and Google Maps, by 2.5%, +/- 0.1%.
Has anyone else-before or after the NTB11-041 update-seen this same odometer/CW mileage disparity?
Do you suppose this may reflect the similar discrepancy between the dash and screen numbers, as widely reported?
My car has consistently shown 4.3 m/kWh on the dash and 4.4 on the screen, for months now, as my average since delivery.
So, from the limited info I can gather, looks to me that Carwings may now (since the update) be accurate as to energy use, but underreporting my car’s miles driven, and m/kWh, by 2.5%.
Carwings rankings below show the result since my 8/3 update, when CW was (almost?) corrected.
