On my new 2009 TCH, I go into the
Trip Information -> Fuel Consumption
display and it shows "Best" and "Average". Is that the best on the trip? Best since ? or what? The manual is not clear on this. Any way to see the best mileage I got on the last trip or a previous trip? And it doesn't show any interval with better than 60mpg even when I coasted down a long hill on the interstate.

I searched this forum but couldn't find an answer.
