Milage Until Empty

So the digital range formula sees to be:

Display Range "Miles" after fill up = (21 gallons - (60 miles of reserve / current "avg." MPG)) / current avg. MPG

So despite anyone's avg mpg it seems we all should have about 60 miles of reserve fuel. Be it 3, 4, 5 or 6 gallons in reserve.
