Speed Vs. MPG

2011 Ford F-150 XL
6.5' bed
4X2
5.0 L V8
3.73 rears
Tuner: SCT
Gas: 91
90 KM/H (56 mph) 25.7 MPG
100 KM/H (62.15 mph) 23.5 MPG
105 KM/H (65 mph) 20.8 MPG
110 KM/H (68 mph) 20.1 MPG
The MPG numbers were taken from the computer, after I changed the 'units' from 'Metric' to 'US'. I spent 10 MILES at each given speed. Cruise control was used 100% of the time.
Just as I suspected, 100 KM/H was the best speed because my RPMs were at roughly 1,750 which I think is a sweet spot for the truck.
Here's the video report

Can someone please tell me what the point of this thread is? There's a lot of data here, but aside from showing that slower driving equals better mpg, what good is all the info if nobody is tabulating and analyzing it.
I don't mean to be rude in any way, I just don't get it.

The point is that either some EB owners are inflating their numbers for whatever reason or ford needs to address the huge difference in mileage. Seriously, how can a truck with 3.73 gearing get 1-2 mpg better at 70 than a truck with 3.55.
