Richard,
This engine is spotless. Nothing to comment on except I expected the TBN to stabilize some. The adds are really being used up while providing great protection. I suppose its academic as the SJ M1 is not in production.
Nox and Oxd would help me determine what is being affected in the adds.
Silicon trending up with Iron (I'm splitting hairs here). I think you have a very small or intermittent air intake leak, could also be in a PVC line, grommet, etc. That would explain the TBN drop, dispersants being used to encapsulate the dirt depleting the oil somewhat. Check closely for a really inconspicuous leak.
Overall superior cleanliness and condition for oil and engine.
