1h45m at supercharger, depending on charging curve, should result in 200-300 miles. So maybe you were just queueing at supercharger or something else doesn't check out at all.
Assuming rather low 50kW charge rate thats at least 87.5kWh of energy. Thats 500km of highway range. Assuming more average 75kW rate - 130kwh or almost 900kms. And you are claiming you done this in one day?
It was a 5 day trip. Hertz didn't deliver the car until late on the second day, so that's 4 days. I think I charged on the second and fourth days? I don't know, believe it or don't. I'm not going to put in effort to convince you.
