I ride about 200 miles before I fuel up. Today I went 220.1 miles before fueling and squeezed 4.77 gallons into the tank. I reset my trip A each fillup and reset my powervision as well. The PV shows gallons used as well as mileage traveled. So far the fuel used matches what it takes to fuel up . I have squeezed 5.1 gallons into the tank at a fuel up before.
