The inaccuracy of a fill will be magnified by the smaller the fill. If you assume a full tank will be off by say .25 gallons from one fill to another, then adding only 5 gallons to reach full means a possible 5% error. By filling with 10 gallons, the potential .25 gallon error is only 2.5%. Clear as mud, right?
