You can call me a liar if you wish it doesn't bother me but isn't it possible some of us are experiencing poor fuel economy for reasons out of our control.
I am not calling you a liar, the problem with your analysis is that you mistake 65 and 70 as the same thing, when the difference in fuel economy between 65 and 70 is ~ 9% worse fuel economy:
