We as a collective are not on the same page with MPG
Yep. We didn't buy these cars for fuel efficiency, but I have to call BS on anyone who claims more than 25 mpg in these cars. Why? Because if you're using your info center and seeing 31mpg in a GT500KR SuperDuperSnake, you are not getting accurate mpg for your car.
Sure maybe over that 1600ft of road that you checked the 'guage', but your car is NOT a 31mpg vehicle LOL! Why?
The true estimate of mpg is per tank. I think it's safe to assume that that's what most are implying when speaking of mpg? If not, MPG is a gray term being thrown about carelessly to make people feel good. Kinda like getting a dyno tune on a dynojet vs. mustang dyno and ignoring the latter's numbers because the former's numbers make you feel better?
Reality: Our tanks are 16 gallons. I calculate MPG based on how many miles I can drive on a single tank of gas. So say, I drove 340 mi prior to filling up and I put in 15 gal (I've been estimating mine for over 4 years now just cause I'm cooler than you j/k!!!!). That would mean my REAL (hit me on the head and it'll hurt real) MPG is 22.7 MPG. With 60% city, this is basically my run/fill up routine (340ish miles and 15ish gallons at fill up time).
340 miles outta a 16 gal tank in a Mustang is f'n awesome! In order for that GT500KRX10 car could get 31 mpg is if he/she drove 465 mi on a single tank and assuming 15 gal to fill up. BEEEE-EEEESSSSS!
I average 23mpg (345mi per tank) and that includes burnouts cause they put a smile on my face and I can't help myself LOL!
My info center said 37mpg once but I understand that was only for the portion of road I was travelling on at the time. My car is NOT a 37mpg car. It is a 23mpg car. Do you think the Gt500 owner is fooling himself? I bet if he calculated to get REAL mpg, he's no where NEAR 31mpg.
Just funny. But, hey, I'd prolly go with the dynojet numbers for my dyno numbers myself LOL!
Am I wrong in determining my car's mpg? Or is mpg gonna be a floating number for ever?

If you quit hitting the reset button the MPG will average out. My combined mileage displayed is within about 1/2 gallon calculated. I calculated 19 mpg yesterday. The computer says 18.6. Pretty close. That 18.6 is over a 2 month period.
If I hit the reset button while driving 60mph down the highway it will give extremely high mpg figures for awhile. Same goes for reset right before heading down 1/4 mile at the racetrack. Leave it alone and it averages out over time.

Your logic is faulted. Your car's MPG is a figure which, hand in hand, has to be delivered with an average speed, as the manufacturers do.
"Your" 23mpg average includes burnouts and, I suspect, moments of WOT and general tomfoolery. Well, that 23mpg is your average, not ours. To use your own data as a sweeping generalization on all Mustangs is absurd.
Engage Cruise and take a long ride on the highway. Then take the car on the track and reef on it all day long.
There is no firm average MPG on these vehicles, it's about how you drive them, not what they are.
If you don't believe your V6 can return 25mpg average over a tank, then try driving it more smoothly and within the law, you might be surprised.

Sooooooo....Pushing the gas harder/faster=less MPG? Whodathunkit.

If you want to increase your MPG, even in city driving (I include rush hour bumper to bumper traffic on the FREEWAY as city miles, not highway miles), you can hyper-mile it.
This is probably easier to do in a manual because when you are on a downhill slope of a road, you can step on the clutch and your engine will release from load and drop down to a low idle, 500-750 RPM.
Hyper-mile driving will increase your MPG and you can actually see much more than advertised 31MPG on hwy miles

I agree once again with Alkemist, the only real word numbers are old fashioned hand calcualtions. miles driven to gallons used to refill tank. For example if you drive 285 miles and you fill up adding 15 gallons you got 19miles per gallon.
