yeah, I'd like to see that too
I know this is the 05-09 Forum but my '10 has the same engine so here are some more numbers for comparison. I have the 3.31 gears, Roush CAI but other than that the car is 100% stock.
I've tracked my gas since I got the car (used) in May '10; total of 34 fill-ups and 9333 miles in that time. My GT is my daily driver. Some of the key conclusions:
Overall average MPG: 23.7 (mix of highway and around town, I would guesstimate roughly 50/50 highway/backroads, not a lot of stop & go)
Best MPG on a fill-up: 26 (mostly commuting, highway and back-roads cruising)
Worst MPG on a fill-up: 18.7 (around town)
Best MPG on the computer in realistic situation: 31.0 (for a full commute to work, from my driveway to the parking lot, including about 60% highway at 70 MPH and 40% off-highway at about 40-50 MPH, 10 stopsigns/stoplights)
The trip computer usually reads 0.2 MPG higher than calculated based on a tankfull; sometimes it is low and sometimes it is higher than that; overall average the trip computer is 0.3 MPG lower than calculated (I haven't quite figured out how that can be yet). In general I'd say the computer is pretty close, within a few tenths of the measured/calculated MPG.
I generally drive pretty conservatively though I do have some fun here and there when I see an opportunity such as highway on-ramps. For normal cruising I up-shift around 2000-2500 RPM. I coast in neutral whenever I see the opportunity -- on downhills, when approaching a stop sign, etc. On the highway I cruise at about 70 MPH which is right around 2000 RPM in 5th with my 3.31 gears. I generally try to avoid hitting the brakes whenever possible/safe (this drives my wife nuts, she thinks I should over-react and slam on the brakes whenever there is a brake-light or slow down visible ahead, even if it is 1/2 mile ahead with open space on an up-hill)
Flagstang, you seem to be the MPG champion here -- how do you do it; what mods have been done to the car and/or how to you drive?

My best (pre Whipple) was 29.2 mpg on a long hwy trip. I came close to that a bunch of time, but that was the best whole tank avg. (Calculated Manually - I've had the Dash reading north of 34mpg)
My avg mixed driving (farm country) was around 23-24mpg (pre blower - Calc Manually).
Post blower I'm luck to see 18mpg in my mixed driving.. with a best of 23mpg on the trip home from the Carlisle all Ford Nationals.
