The oil analysis can't prove that the bearings are fine. It can show when they're in real trouble.
A friend with an S65 had been doing regular analysis of the oil. Always came back good, with a glowing review how the wear metals were similar or better than average. He noticed a new noise one day and decided he'd pull the caps and have a look anyways. They were worn through most of the bearing layers, almost down to the backing material. Very smoothly, evenly worn. The crank was fine. New bearings went in. The noise didn't go away, it was something else.
