Well my car was service over the weekend. The fine people at the Atlanta Service Center had it plugged into a 110. I could tell on my tesla app. I had been stuck on 236/237 rated range for a month or so. On the 110 it magically charged to 242. When I got it home I plugged it into my 14-50 outlet and it charged to 242. I wonder if the long 48 hour charge on the 110 conditioned the battery. It too about 48 hours to charge from where it was at.
