It's not a matter of faith. Checking and calibrating one's equipment negates the need for faith.
It's not that I don't trust open aperture metering ... I'm just trying to see if there's any significant difference in results between open aperture and stopped down readings, which is actually incidental to the original intent of comparing two lenses which are said to be the same optically, one of which operates with stop down metering.
