Are SOC% and MTE both only a[[rocimate readings? Both would seem to be calculations based on some assumed average. If I only had SOC% I suspect I woulf quickly learn to translate it into miles remaining. Neither can be exact.
SOC is the more likely of the two to be a measurement, and in and case more reliable. The MTE would fluctuate depending on the efficiency being assumed. A change in driving conditions, like slowing down, can lead to the MTE going up, even as the SOC is going down.
Bottom line, I
know how much charge I have left (more or less), but I don't
know how far I can drive on that charge - just a reasonable guess. Hence the term "guess-o-meter" or GOM for short.
