If you want to be more accurate with your mpg calculations just calculate less often. Instead of calculating based on 300 miles go 1200 or 1500 or 15000 miles. So fill up however you choose, reset your trip odometer, drive, keep track of all the fuel you put in, not bothering to fill up in any particular manner until the last fill up, at which time you fill up the way you did the first time. Calculate, and your going to be very close. One thing I like to do to get an accurate mpg figure is start my test with a clean DPF and end the same way.
