Here in New Jersey...I....uh..don't pump the gas myself.
There's always a small amount of topping off but I've never seen the car take more than 11.5.

I recommend liberal use of increased playback speed.

Like I said I almost always fill up at Costco where I can't top of anyways. But in the name of science.

There's really a usable of 13.2 since that's the tank size. Not sure how you come to only having 10 gallons of usable fuel?
If he can only fill 10, he can only use 10. I think realistically any pump will let you fill from bone dry to 11, but 13.2 does seem to be nearly unreachable via most pumps.

usable and absolute are different measures. Your usable also depends on how comfortable you are with fumes
People, you need to remember a fuel gauge is an approximate indicator. It's not designed to give pinpoint accurate readings like a tach or speedo. Every car is a bit different so it's a matter of getting accustomed to how the gauge functions.
Mine has been pretty accurate since day 1. I fill up with about 12 gallons when it's between about an 1/8 and reserve. I pay little attention to "miles left" as that is a running average at that specific point and time. I glance at it, but it's merely a gauge also as I can extend or hold or decrease the miles left based on throttle inputs. Again, that number of mile left is not to be taken as absolute. It's a guide, an indicator, but by no means is it 100% accurate.
Now if you are experiencing numbers that don't add up, then you might have an issue with the sending unit or gauge just like the recall. If you are sitting on E and only putting in 9-10 gallons of fuel and are sure the pump is functioning properly then you should have it checked out. But for all of you who are expecting it to be accurate within a few ounces, not going to happen.
It is interesting about the VW Connect app giving a bit more accurate info. Obviously it's taking a more precise reading electronically, independent of throttle and other driver inputs, etc.

Drops quickly because the pump didn't let you fill it up. So what you're seeing is just the gauge somewhat accurately catching up to a tank that is only 85%ish full.
I will also add that every time you fill up you are not putting in the same amount of fuel as your prior fill up. It will vary a bit based on the pump, time of day and weather. It's not going to be a lot, but every pump will be a bit different if you are relying on the pump shut off. So that right there already causes some issues tracking fuel, even if you hand calculate.
I personally put in an extra 1/2 gallon after it first clicks off.

Yes about the approx and mine is also reasonably accurate. I do find it's mpg reading about 2 mpg optimistic. but till I get bored and obd11 it's OK.
VW connect app....I can't imagine paying for it. Got a msg the other day where it said your windows are down and rain is in the area. The randow warnings fo windows down and unlocked are just crying wolf. The idea is good but execution is poor. I wonder if the app is better as I see range gets rounded off to 5 mile numbers on the car display?
I would love a believable rain and windows down warning (still too cheap to pay $100 year even if it was perfect)
