It seems oil threads will never die... For the record I learned quite a bit from this exercise and from researching to understand the results of the test. And to some extent it was true that knowing the ppm of a bunch of things does not necessarily tell you much without a lot more information. But I learned a lot of things about oil that I didn't know. And in the end I think the truth was the oil was not nearly as "still good" as I thought. The TBN was getting low, it had a good amount of fuel in it since I do lots of short trips. It was still good but not for too much longer. As far as the previous example, it is kind of like saying "I brush my teeth 3 times a day and I have bad teeth so you should brush your teeth 6 times a day". Maybe, maybe not. I feel confident I can go 10K miles with this oil in this engine. But it might not be great idea in every engine.
