Slow Supercharging?

So I'm at a Supercharging station with no one charging next to me. Everyone is in a different #. It's about 70 degrees outside. This never happened before...

My LR usually charges above 450mph but every time I plug into the super chargers at the Houston North service center it only pulls around 158mph. Yesterday I made sure no one was plugged into the other paired charger and it was still that low. Maybe some stations are just lower amperage?
