Add EPA starting range to the battery report

I did not join TeslaFi until I had 7k miles on my car. by that time my battery had already degraded from the EPA default of 310 @100% to 285 miles @ 100%... so all my percentages are off because the "High range" is off.   Can you please make the chart and calculations use the "factory" range and not the first range when we sign up for TeslaFi.

Thank you!!
