There's no misunderstanding "get 75% of their rulings reversed." Read literally, it is quite untrue. The Supreme Court generally grants certiorari only when there is a split amongst the circuits, or (more rarely) all the circuits fundamentally misread the Supreme Court. Only a very small percentage of cases which are appealed to the Supreme Court make it onto its docket - approximately 7500 cert. petitions are sent to the Supreme Court each year; only about 100 or 150 are ever granted. That is, of course, far too small a sample to use to impugn the 9th Circuit. The Supreme Court chooses only the more knife-edge cases which the Circuits couldn't resolve on their own.
Whatever floats your boat.
