Particulate count was consistent no matter what the RPM of the engine for a given load, essentially stating the higher the RPM, they found the lower the wear per stroke.

Love to see this. they have repealed the law of physics here if that is what they are saying. Load and stress on all metal structures within an engine increases as RPM increases. Again, if high RPMS were GOOD for an engine, race car engines would last forever. They don't, not even for weeks.
BTW-wear is measured by things other than particulates in the oil.
