I feel you... I kinda see what u mean. He's trying to test accuracy in the sense of 15 gallons equals 333 mi. At 22.1 mpg. But the computer keeps a reoccuring track of the gas.
So let's say he started doing that with 200 miles on the car. But never calculated from 0 miles. Wouldn't that be his .7mi difference? Its really a small number. I think if he kept doing it for a few thousand miles. Eventually he will become accuate by .1. That's kinda the point I'm makin.
Feel me?
