You miss understood what I was saying, your gas in the tank is subject to temperature changes. Have you ever noticed sometimes when you park your car in the afternoon you notice your fuel level and the next morning when you get in your gauge shows a different level? Even if the fuel pump is temperature compensated your gas tank is not. So depending on what temperature you fill your tank at could affect how much you put in. Also as you may have noticed the shutoff on some pumps are more sensitive than others and could shut off sooner. Too many things can affect how you fill the tank that will cause errors in manual calculations. Like I said you can never be sure you filled the tank exactly the same every time.
