But your results have me thinking maybe I should get mine done on next change (damn, just changed oil)... poor thing sits more than I would like. Though I do drive it hard when I do get her out. Hah, mine has been getting <2500 mile oil changes for the last few years. Yes, I know I'm probably wasting money... but it helps me sleep better.

OP already got 4 analysis to be able to see a trend - not sure if another one will yield any more useful info. I'm not sure I understand the logic from Blackstone's recommendation for cutting back the oil change interval at this point. Sure, cutting back the change interval will result in lower wear content shown on the next analysis, but it doesn't prevent the fact that the problem is already present.

If you look at the oil analysis on my S54 M Coupe attached, you may think it's fine based on the last analysis on 1/14/2018. But look at my bearings when I pulled it out just after that analysis at ~55k miles.

Oil analysis needs to be use regularly and you need to look for trends. I've seen plenty of people that get oil analysis regularly, but then won't do anything when they see a problem or that they'll just do spot checks, which won't provide any useful results.
