I took a look at the spreadsheet and have a few comments. Right now there is no calculation based on metered kWh if available. It seems like no one else is using metered kWh right now, but it is the most accurate way of tracking power since charging losses are otherwise estimated. Charging losses are estimated to be 15%, meaning 85% of the kWh makes it to the battery. The calculation right now is kWh * 1.15, but that is not equivalent. It should either be: kWh / 0.85 kWh * (1/0.85) ~= kWh * 1.176 Misleading calculations. I think the only calculation that is meaningful here is MPGe, otherwise: EV Miles/kWh, Miles/Gal Equiv, kWh/100mi are all misleading calculations, since EV miles only counts miles in EV mode w/o blending, but kWh counts all electricity used, regardless of mode and blending. HV MPG is misleading because HV miles includes blended miles. There should be columns for $/kWh and $/gallon and the $/Mile should be based off of this (or default to the national average if this is not available).
