I don't know the answer to your question. It's very complex. If Badds had 3" more left lateral hip slide, then it may affect his hand arc at the start of the downswing if the lower body shift affected the upper body's motion in space. That depends on the degree of dynamic X-factor - the amount of torso-pelvic separation at the start of the downswing. Some golfers have a lot of dynamic X-factor, and an additional amount of left-lateral pelvic shift-rotation may not influence the movement of the left shoulder socket in space, while other golfers have little dynamic X-factor and their shoulders move rapidly in response to any pelvic-shift rotation movement. There is presumably also variations in the degree of secondary axis tilt occurring with a greater amount of left-lateral pelvic slide and that may affect the angle of the shoulder's axis of rotation around the spine. I do not have the insight to compute all these confounding variables and make a rational outcome prediction.
