OK, I did a REAL WORLD TEST. I reset the dash trip reading and then filled the tank and then reset the trip to zero and calculated it on the refill.
Here is what I got:
DASH DISPLAY = 29.4 MPG
HAND CALCULATION = 29.8 MPG (6.9 Gallons of fuel burned at 208 miles with Costco Top Tier 91 octane fuel)
2016 CX5 GT- AWD - Roof Rack (no cross rails), OEM Mudflaps
I will do one more 200+ mile run and see what I get.

- A few WOT runs
- About 15 minutes idling in park
