Let's not be too silly. In the R1T Large context a percent is 3.14 (pi!) miles EPA. If you have 15% battery left you have a range of 45 miles. If your next leg is 190 miles you know you have to charge 63% and if you know your charger does the nominal 1C charge that it's going to take 63% of an hour (38 min) to pick it up.

The EPA consumption is simply 135000/314 = 430 Wh/mi. If you know it is going to rain on this next leg and have learned from experience that this usually adds 30 Wh/mi to rolling resistance then it's apparent that CONSUMPTION is going to be about 8% higher than EPA and so you had better add 8% to your charging time and make it 41 minutes.

Can you figure this out using harmonic arithmetic? Sure but why do it the hard way? The rest of the world has figured this out. Why can't we?
You lost me.

That's not what I wanted to do!. I can try to explain it more clearly if you tell me where you got lost.
