I have added to my post above a third change that Katie made in her Golf Stroke. For convenience, I am reprinting the edited paragraph here:

Three of the major changes I am proud of are her Grip, Pivot and Finish. Her right hand used to be well-Turned (to the right), so much so that it was almost parallel to the Plane. With lots of practice, she fixed that in a couple of sessions.

Her Pivot was virtually non-existent: Her Foot and Knee Action were minimal, and her Hip and Shoulder Turns were restricted, all of which limited her Power and contributed to Plane problems. A disciplined application of the MacDonald Drills transformed her Motion and helped her Timing. In the past month, we removed the tilt from her Backstroke Turns.

Finally, her Finish used to be 'sawed off' and very 'blocky' (no Arm/Hand Rotation). She quickly learned a correct Finish Swivel out of the Follow-Through (Both Arms Straight position) and to pose in a professional Finish (with due attention to the five Finish alignments of 12-3). As she learned to 'free-wheel', she went from hitting weak Fades to strong Draws.
