^It makes sense. After reading through the article Pablo gave as well as doing some research, i have to agree with what you said.
The oil is acidic in the beginning and that helps it quickly clean and dissolve leftovers left behind by the previous oil.
TAN quickly drops and then slowly starts going back up as the oil ages and nears the end of its useful life (additives nearly gone)
If i was to sample the AZO after 1,000 miles, TAN will be considerably lower.
