Read the articles on the bitog homepage by Dnewton. Enlightening info.
And throw your money away if you like. I'm confident its not going to help re-sale value.
I have no qualms pushing the OCI to the full 10k mile OCI recommended by Ford if the UOAs show it to be appropriate. The 2200 mile change this time around was intended to get rid of some of the early wear metals. If I go with an 8k change next time around with the OLM showing some life left it will simply be to verify that the oil is holding up and to satisfy my own level of OCD.

Yep, meant 5w-20 synthetic blend.

I'm sampling, not changing my Ford, to get a feel of whether I can trust the oil life guesser. I assume its relatively easy for the OLM to guess a change if you have a prosaic driving pattern. It might be right just out of happenstance. The challenge to their algorithm is for us outliers.
There's no need to try to go to the bitter end every oil change, but adopting an absurdly short interval with that size sump would get pretty expensive.
Yes, the 8 qt sump on this car is bigger than any I've ever owned. While I don't plan on doing routine 2200 mile OCIs I will likely do a UOA with each change which is probably just as absurd, but once again satisfies my level of OCD. It'll be interesting to see how much the amount of "spirited driving" affects the UOAs as well as the OLM readings.

You think the TBN would have been deleted in 2,200 miles?
We know the oil was changed early but I have no problem with that.
The viscosity loss is nothing to be concerned about particularly for the way the car is driven. Oil shear often occurs early then stabilizes.
No, of course not. My point was more to the point that an UOA of a FF can not tell anything about the capability of the oil to perform properly. I have no problem with someone spending the money on UOA's of FF but there is nothing to be learned about the oil or health of the engine so early in its life.
I definitely wasn't expecting to get anything from this UOA other than a baseline for the next change. I plan on including the TBN next time around and have no problems pushing the oil to the full 10k interval after that if the UOA and OLM both point in that direction.
