Not my job. Isn't that what the handicap committee does?

Handicap committee evaluates data but does not generate it. As well designed as the propeller appears to be, I would think the 4% described is really high. Maybe Sean can provide a link to this data that he apparently has seen. I would agree that it certainly does not help performance.
It is also possible that the HC committee took no action for the simple reason that no one asked them to.
