I filled up last night and my Avg MPG display indicated 26.2 mpg, my gas consumption compared to mileage calculated out to 27.3 mpg, so the the computer was only off by about 1.1 mpg.
That tank of gas included a good mix of driving, everything from a Yawn Crawl out of Los Angeles to the burbs, racing up to the Lake as fast as possible on Saturday, practicing the occasional launch, and just plain old driving to work, then to the GFs place and home again which is mostly freeway but a good bit of residential at both ends of the freeway.

*Pokes head in looks around* Yup still Mustang Forums! Dayum, had to check again, feels like I've entered a prius forum or something 
Anyways. Couple of things to remeber about real world MPG.
Fuel changes forumlation ever so slightly from Winter to summer and vice-versa, this will affect MPG (section 3-7 / 3-8).

The report itself is vague on how the changes in forumlation affect Engine economy. They state Engine Performance....that could be interpreted in many, many ways and that's just what they want.
There are also different formulations of gasoline from state-to-state and even one region to another depending on state and federal requirements.
So my point is, you really can't compare MPG between one car in one state and another car in another state. Too many variables (driving habits being a big one too). What you can do is get a baseline for yourself and see how different things affect your gas mileage. For me, dirty fuel filter and dirty air filters are noticiable. I also noticed when the switch from Winter gas to Summer gas occurred.

I got a 2012 v6 PP last oct. The MPG display fluctuates between shows 22 to 22.5. I have never actually reset it. My usual highway speed is 80mph and I do tend to drive the car hard. Maybe you can do better driving slower? Personally I am cool with what it is.
