I should clarify, I've had other mpg gauges in my car and various fillups so I already have a good idea what mpg it should be @50mph. The adjustment isn't technically random, you adjust the vss and the microseconds/gallon up or down by the percentage that the display is off. Same technique will apply at fillup, except it should be possible to get the computer to help out a little.
