9 mpg doing 60 and not being able to comfortably hold it up a hill or merge onto the interstate vs. 11 mpg doing 70 and easily holding it up a hill or accelerating is a pretty big difference.
My fuel economy is quite normal. Go look at any EcoBoost forum or group on Facebook and you will find no shortage of people getting similar numbers. You have to remember not everyone is driving a lifted 4x4 with oversized tired and a metric ton of "expo" **** bolted to it.
No idea why you had such an issue holding speed. My truck could easily hold its speed going up to 7000 foot passes.
