Please help, from what I understand as long as you can charge in either 1a or 1b and no one else in charging in the other stall you should be good. Today in Culver city, I tried charging at 1a and was getting 180 miles per hour. I decided to move to 1b and started getting 225mph. Why the discrepancy? Next to these was 2a which was empty and someone was charging in 2b next to that. What is the best strategy to maximize charge speed?
