My current real world fuel economy

Using OBD generated data:
When I take my foot off the gas going downhill I'll see over 100 "Instantaneous" MPGs...and then when I depress my clutch that number will shoot up to over 150 MPGs.
Also, the OBD reported 19.6 overall AVG MPGs is a good 2+ MPGs over my hand calculated avg which is closer to 17.5.
Hoping the fallacy is evident here, eh?

I should add that my truck sports an above cab topper which doesn't help fuel economy at all, but does provide needed security from idiots as well as the elements.

Looking forward to hearing what the new Gen 2.5 & 3 get when traveling @80mph for 300+ miles.
Yeah/obviously, 55mph will maximize MPGs, but at the expense of 25 minutes of extra driving per hour compared to 80mph is just not a tradeoff I'll make when it comes to arriving at my long-ish distance destination a fair bit sooner when an interstate hwy is a viable choice.
 
Real-world fuel economy is hand calculated. Regardless, it is what it is. Fill up and go - rinse & repeat. YadaX3...

Gen 2 6-sp:
Honestly, cruising in 5th instead of 6th hadn't even occurred to me as far as real-world testing. To begin with, I'm so seldom on 55mph-65mph roads for any extended traveling. My best MPG to date was 21.7 on a Thanksgiving roundtrip using a rural hwy averaging 60-65 mph - using Winter blended gas, too.
 
Real world fuel economy involves doing arithmetic after filling up...not reading a display while coasting.
