The oil analysis is great but by the time you get the results telling you there is an issue the damage is already going to be done.
Justin's report is almost perfect much the same as all the rest. There is just no evidence at all (at this point) that there is any gradual wear happening.

What is the pattern you are seeing? RTV or failures?

Problem is that we have not seen any UOA of the failed engines while it was still running (or again, maybe i missed this info?) thus we do not know if they were suffering from a gradual slow death. All the positive UOAs that we have seen thus far are from engines that have not failed and very well might never fail. What i am seeing is that more evidence suggests that RTV is not causing premature wear so these spun bearings is likely not related.
