partical fills can be added, if your accounting for them in the total MPG avg count then there is no reason not to tally on a full fill.
the Miles only need to be counted from last fill to current fill and then total the gallons and divide. I am going to assume that all this is kept in some sort of DB and you can set a flag on a partical just like you would on a skip.
That's ok, we can agree to disagree on this one. Tracking your fuel based on a full tank isn't a science, and there's no way to be 100% accurate without some sort of device attached to your vehicle measuring fuel consumption. So we have a system that we worked out for getting an estimate, and I'm sure there are lots of other ways you could do it.
Ok that comes to 1680 Miles from last fill (odo reading 92838), 94.86 Gals, thats 17.71 MPG.
Now what would be the differnace if I just entered 1 fill at 94.86 Gallons and a Odo reading of my last fill ? because I am just trying to wrap my head around the idea about how you are handling the part fills.
BTW - I am not picking on you or the site, I am just trying to help this work more smoothly. I have records of every fill for my car from the 116 miles that were on it when I picked it up, to the current almost 95k miles. In that, I dont have records of I think 3 fills.
