Yes. You got it. That calculation is based on driving a certain way the EPA does. Which is a lot slower than you were going and no heat on. If the EPA says a gas car will get 34mpg highway and will do 180 miles with 3/4 tank. But your driving style only netted you an average of 20 mpg you won’t make the destination either.

So yes in 6 weeks you should have know what your WH per miles are. You should have known when the wh/mike reads anything more than 250 you aren’t getting what the battery meter miles is showing. I figured that out in 3 days on a rental Turo before I even bought my actual car.

So if you haven’t in 6 weeks you are absolutely right.
