Okay, I don't care if there were a thousand.
52kW is not what you should be expecting at a 250kW Supercharger,
Wait a sec, 88%? No wonder there are long lines, you shouldn't be charging above 80% at a Supercharger, and you should be starting at 50%.
If you want speed, you would charge from 5% to 50%. That takes probably a third of the time that 50% to 90% takes.
