Shiner you are misusing data to try to proof something to be that isn’t. You just have to trust me when I say the increase in fuel economy from the 17 to 21 Powerstroke is astounding. I feel like I’m standing in front of a hippopotamus and you’re convinced you can get me to believe I’m looking at a giraffe.
So you are telling me I cannot trust Fuelly, not trust the EPA fuel mileage test(which Ford performs) from other 6 to 10 speed vehicles, not trust all our fleet data from our 10-speed half tons and Superduty's, not trust ZF and many other transmission manufacturers, but trust TFL and you when you say you a 10-speed transmission increased your fuel mileage 23%. Sorry, but no. And I don't even think Ford would back you in saying that a 10-speed transmission increases fuel mileage by more 10% let alone 23% like you are claiming. In fact, if I remember correctly from of their slides about the 10 speed, even they said expected fuel mileage increase of 6-7%.
