When I get my self better organized and a kill-a-watt meter on the charger for my comuta-car, I plan to keep track of power going in to the charger, it sounds like your formula is assuming that people are tracking the watt hours as it comes out of the batteries, not what it takes to charge the vehicle and that charging is what people tend to keep track of, energy in and miles driven.
