Use wet-wedge consistency as a fitting tiebreaker
In this wet partial-wedge test, the set wedge lost friction and launched higher while the SM9 gained friction and launched lower. The instructor says the SM9 performed best in the wet and cites a 113-versus-493 standard-deviation comparison plus zero yardage standard deviation. Because clean full swings were nearly even and both partial options performed well, the wet result and his preferred Vokey turf interaction decided his choice.
