Well it’s been almost 3000 miles and at least seven tanks of gas, and it is hit or miss on whether or not I get a fairly accurate reading on my miles per gallon. It is usually running about 2 miles per gallon high on the overall per tank value vs hand calc. How can I adjust this down even 1 mile per gallon and maybe it could learn the rest? Any help is appreciated.

Edit, I am of course referring to the “since refuel” screen.
