Looks excellent to me with no problem at all. I think 7500 miles seems like the right change interval to make it last forever with this oil.
The sodium is a little off at 14 but I have seen VOA's of Mobil 1 as high as 11.

TR3-2001SE:
Please permit me a minor nitpick.
Based on the previous UOA it looks like his TBN will hit 2.1 right around the 10K mark, and of course a TBN of 2.0 is where you want to change out.. Nothing besides TBN is even approaching a condemnation point at 10K.
