Can you explain how 'usable battery level' is sourced. I've checked twice today and it matches my energy chart+ consumption+30 miles+average (vs instant) .. "Projected Range" exactly. Maybe popup/hover help box over it?
Is this "Useable" calculation based on Temperature, efficiency, degradation?
Yes, please define usable. Tesla sometimes shows battery capacity locked out due to cold, etc but I don't think that's what you're referencing here...
