In the Golfing Machine- Delivery Paths refer to the motion the hands make on the incline plane. It doesn't refer to the right shoulder. Regardless of the path the hands take - on the simplest procedural level- it would be that you either try to move them on a straight path or you try to move them on a circle path OR you might feel them move on a straight line path or feel them move on a circular path. Either way, besides video you may want to see their visual equivalent on the ground as you make both motions.
