@rallison Your car was changed to track in KM - at the top of your car profile there is an Edit link that gives you some car specific preferences. I flipped your car back of to Miles and performed a re-calc and your Avg MPG is back up to 46.8 with your most recent at 51.2 MPG. Sorry for the delay and let us know if you run into any more issues.
Odd; that change was not intentional, that's for sure. Thank you for finding the cause (even if it turned out to be the chair-to-keyboard interface) and correcting it!
I also have miscalulations on my l/km info and also my km have changed to miles??? was getting about 7.6 l per 100 km now getting 17.25 l per 100km. PLEASE correct this error. Thanks.
