Report says Synpower, it's actually about a 50/50 mix of some leftover Synpower and NAPA syn (similar formulas). Filter was NAPA Gold.

Any concerns with the copper?

I've heard differing opinions on TAN/TBN. Some say ignore the TAN and change when TBN gets to 1.0. I've heard others say the oil is shot when the TAN exceeds the TBN. Thoughts?

Anyone foresee issues extending to 7500 with this oil?

You sure you made that google doc public?

Must have as it just opened for me.

Your oil on this run was far from shot. Go ahead with the 7.5K OCI recommendation there is plenty of TBN in reserve and all the wear metals were still in single digits.
