Took our first long weekend trip this weekend, 435 miles each way, about 900 miles total. Everything was great and the whole range anxiety is overstated and unnecessary.

Anyways two questions came up.
1. Driving back last night, the route had us making two stops, before planning to arrive home with 15% SOC. At the second charge I disconnected 4 min early, as the Navi/trip planner in the car was showing us arriving home at 10% (I figured that would be plenty overhead). So had I charged the full required time (4 extra minutes), I would then theoretically depart this second supercharger with enough battery to arrive home with 15%. BUT, either immediately or within less than a mile (I didn’t even make it back to the interstate exit), when clicking on and expanding the route on the car screen, it said that we would arrive home with 21%, which we did. And this last stop was like 150 mi or so from home. So, where did that extra roughly 10% come from?

2. I’m on the East Coast and drove north through NY State. Just curious, I thought the supercharger pricing was approx. $0.28/kW. Was surprised to see either $0.45 or $0.48 / kW. Have the rates gone up? Are they time based?

Thanks!
