I charge to 90% Usually by the time I get to my car it can be anywhere from 212 - 213 depending on when it finished charging.
Needed very little juice last night so it was charged early. Got in my car at 7:30 AM (little late for me) and I was at 214.
So, yeah. I think the same has happened to me, but, not on the same scale. Will take a closer look at the numbers tomorrow.
