For a hypothetical eight-hour window, the saved source fixed Level One rate four miles per hour gives thirty-two miles. Fixed Level Two twenty-eight gives two hundred twenty-four. Bars share zero at two pixels per overnight mile. These rates are programmed assumptions, not a measured charger or vehicle guarantee. Actual power, vehicle efficiency and conditions remain unverified. At thirty-five hypothetical daily miles, thirty-two modeled replenished miles do not cover the daily distance. The source sufficient condition compares replenishment greater than or equal to entered daily miles. Bars show those values at ten pixels per mile. This explains the executable comparison, not installation advice, actual charging feasibility or a safety assessment. The saved energy-per-mile constant is derived from two hundred four fifty-four divided by thirty-five times three hundred sixty-five times point one five. Feeding those baseline inputs back into annual energy cost produces two hundred four fifty-four. Equal bars at two pixels per annual dollar expose this calibration identity. It is not independent validation of real annual costs. Full native text export and reset remain preserved.
