I don't have to try (and pay) for them to believe the results of truly objective laboratory accuracy tests that show ceramic bearing have a negligiable effect on a bicycles rolling resistance. Your "roll out" measurements are subject to too many uncontrolled and self-serving variables to prove anything to anyone but you.
