Good question.

It would be interesting to check whether Dustin Johnson rotates his pp#3. He arches his wrist from the top. Maybe that enables him to keep pp#3 orientation aft all the time. With a pitch elbow, the degree of cupping /arching could have a huge saying here.

Dustin Johnson actually sets up as Hogan prescribes in 5-Lessons . . . his elbows are WAAAAAAAY together . . . Pitchy at set up . . . His right wrist bends to an extend that that his left wrist is freakishly arched. He keeps that pitch deeeeeeeeeeeeeeeeep into the downswing the pitchy move obviously is a "face opening" move . . . so I wonder if that is a requirement to keep that face "open" . . . but that dude swings the club on plane basically from delivery thru as good as anyone. This is paraphased from the first 3 editions and later taken out . . . but the elbow plane was considered efficient due to the club moving at 90 degrees to the axis. Seems to be what Johnson does. But with that arch move he has to do something to keep the face from flashing so he "leads deep" into the downstroke. The hands path and club move beautiful.

All this aside from the fact that the dude can don't a ball barefooted with no running start . . . athlete.
