You are cooking the books by including service charges/fees in that number, unless you were off grid and had to go on-grid to get an EV. It is far more predictive and genuine to keep them separate. Otherwise it is just nonsense, if an EV doubles your usage, THEN what is your cost/kwh?!? See what I mean? With your oversimplified approach the more you use the less it costs (and is that really the spin you want to put on it?). I'm not saying do it because of feel-goodery, I'm saying it because it is far more accurate.

Most folks seem to think it is good for ~%10 in an EV (perhaps coincidentally I was %12 above EPA yesterday). Also P&G is rather low duty cycle in this (accelerates fast, and glides good). I posted a "bsfc" chart which tells much of the story, plus it is direct drive so it is easy to extrapolate to mph. Try to avoid dead stops, and unnecessary braking, but no reason to be shy of the accelerator if you can glide it out it seems.
