Pivot photos of two typical Golfers are shown below with lines scribed for reference.
The Knee Action Sequence is Identical for Both Players, however the Golfers vary in the degree of Motion.
Both use Standard Knee Action:
Backstroke: Right Knee straightens and Left Knee Bends.
This determines the amount of Hip Slant (Blue :Line) and Also becomes a factor determining Left Heel Rise above ground.
Hip Turn in the Top Sequence is a little less than the Player in the Lower Sequence (Weight Shift)
Both Pass through Sit-Down between Frames 4&5
Both PLANT THE LEFT HEEL BY BENDING THE RIGHT KNEE DURING SIT-DOWN which provides a lateral shift as the Hips continue Leading the Shoulders.
This Hip Action synchronizes the #3 Accumulator Roll through Impact.
Ben Hogan returns His Head to Center of Stance during Sit-Down. Tiger does not. Tiger has his Right Shoulder and Arm On-Plane at Impact. Nicely Physical, but then Zero Right Elbow Bend at Impact.
I wonder if the amount of Knee Bend contributed to Ben Hogans Impact Geometry?
Can the Amount of Lateral Slide be controlled by the Amount of Knee Bend?
