After 24 hours in my car, it has been 156.94 through 2 charges and 2 drives. I'm not sure how Tesla calculates this, but it seems very stable.
It was also 156.99 just three weeks ago - Car doesn't like sitting idle while I'm sick :-(
There are some app changes being made at the moment - once those are done, I'll get it added to the Info screen on the Apps.
