Brian feels he uses his Right Arm a lot during the Impact Interval. That would explain why setting his Right Forearm On Plane at Address these past three years has made such a tremendous difference for him.

Brian is also very well ranked (#5 actually) in the PGA Tours stats in Scrambling and if I remember well, it was also the case last year.
I guess that his right forearm on plane in chipping helps a lot to start the ball consistently on the right track.

I also never saw him much using cut shots with an open-open stance. Instead, I see a lot of square-square + right foream on plane: I remember Dave Pelz in his Short Game bible saying that ball's behaviour (bounce/roll/scatter) was more reliable.
