Efficiency correction for altitude change
It would be a nice touch to correct the calculated efficiency by the difference in altitude between the start and finish of a drive. This is just to accommodate the energy stored or lost in the delta(M*G*h). It needs the mass of the car (specified by the user profile) and the altitudes (evidently in the data).
So a request!

I was perhaps unclear. Going up a hill -- lifting the weight of the car to a higher altitude -- takes energy, stored as potential energy; going down the hill recovers that energy. I live on a hill; when I go down the hill to a store, my claimed efficiency is say 150%. When I return the claimed efficiency is 75%. Since TeslaFi can know the altitude change from available maps, it could correct for this bias in each direction, and that would be nice.
The efficiency is not changed by altitude. Efficiency is how much energy used (no matter the source) over distance.
