Your condescending attitude does nothing to further your credibility. And your inflexibility to criticism is holding you back from improvement. At least you did finally relent the last time we got into a debate about battery charge/ discharge depth versus life cycle. People are not stupid and no one person knows everything. I would hope that you could relax and look at this as an opportunity to notice something that is not quite right with your reporting, and improve.. You are not measuring consumption in any way as you already stated earlier. But maybe now you will find a way to start doing so if you want to persist in making statements about the energy efficiency of the cars that you range test. You are extrapolating consumption based on an assumption of the battery capacity that you have taken from the factory spec sheet. We have actually all heard gas car drivers make the same mistake when they figure their fuel economy based on the spec of their fuel tank capacity instead of reading what the pump says. "My tank holds 10 gallons and I always fill up when the gauge gets to 1/4 so I went XX miles on 7.5 gallons of gas". This might not even be close. That you have speced the Leaf to be 20% less efficient than the Spark should alert you that something is not quite right with these numbers. The most convenient way (and practical way since wall to wheels is the real question in paying for energy) would be to read what the charge station says the same as we do at the pump for gas cars. Charge the car. Drive the car. Charge the car again on a known logging station to read out the consumption. Or, invest in a logging power meter. Or, just refrain from making statements about efficiency since you have not actually measured it and your current method is obviously not giving good results.
