Jeffy is very impressed with Michelle Wie's "new" DH-hand release action that is characterised by a delayed full-roll DH-hand release action.
Jeffy posted this comparison between Michelle Wie and Tiger Woods.
What is the main difference between MW and TW?
Here are capture images from Jeffy's animated gif image.
Note that both golfers have their clubshaft straight-inline with their left arm at P7.2, which means that they are both DHers (who have maintained a stable clubface between P7 and P7.2 and who have avoided flipping of the left wrist and any significant counterclockwise roll of the left arm during that time period).
Note that MW still is manifesting a very stable DH-pattern at P7.5 (image 2) due to the use of a delayed full-roll hand release action while TW is already starting to perform his full-roll DH-hand release action at an earlier stage. Although I favor a delayed full-roll hand release action in golfers who use a full-roll DH-hand release action, it is not a fundamental imperative. Both TW and MW have stable clubfaces throughout the immediate impact zone between P7 and P7.2.
Now, what allows MW to perform such a good quality DH-hand release action?
Here is KM's table of essential swing elements that promote a DH-hand release action.
I will now demonstrate that MW doesn't use those "essential elements" in her DH-hand release action.
Consider MW's address/backswing action.
Note that MW has a neutral 2-3 knuckle left hand grip, and not a strong left hand grip (as recommended by KM for a DHer).
Note that MW has a very extended left arm at address and during her entire backswing action, rather than a slightly bent left arm (slightly flexed left elbow) that is recommended by KM.
Note that MW pronates her left forearm at the start of her backswing and her watchface is parallel to the ball-target line at P1.5 (image 2) and her clubface is very open to the CH arc, and yet that doesn't affect her ability to perform a DH-hand release action.
Now, consider MW's downswing action.
Image 1 shows MW at P4 and image 2 shows MW at ~P5. Note that she seemingly increases her degree of lag between P4 and P5 as she actively adducts the right arm and drops the right elbow actively downwards.
Image 3 shows MW at P5.5/P6. Note that she releases her club very early - manifesting an early random release action. Note that her right elbow is high and far above her right hip joint area and that she is already starting to straighten her right arm and internally rotate her right humerus. In other words, MW manifests an early internal rotation of her right humerus action, which KM wrongly claims will promote a non-DH hand release action. Also, note that MW's clubface is open to the CH arc at the P5.5 position, which KM wrongly claims will predispose to a non-DH hand release action.
Image 4 shows MW at P6.5. Note that her watchface is parallel to the ball-target line and note that she has a GFLW and not a bowed left wrist. In other words, MW is using a late left forearm supination action (which represents the release of PA#3) while maintaining an intact LAFW, and she doesn't manifest an "early left forearm supination + left wrist palmar flexion" phenomenon that KM wrongly asserts is a major/essential biomechanical feature of a DHer.
Finally, note that she has a neutral right forearm in images 3,4 and 5, and not a supinated right forearm.
In summary, MW doesn't manifest any of the most essential elements listed in KM's table and yet she is capable of perfectly performing a DH-hand release action. That proves that KM's opinions regarding the fundamental underlying biomechanics of a DH-hand release action is wrong-headed. I critically analysed KM's opinions re: a DH-hand release action in my latest review paper, and I demonstrated that his biomechanical reasoning is highly flawed.
