I wasn't making any remarks against you - only saying something about science in general.
Air,
I certainly didn't take any offense. I enjoy your inquisitiveness. I just don't have that much to offer other than what I get from the book and the folks here.

I really like tea, A LOT! And that Tea and lemonade cooler mix is awesome!
Now, I'm going to say something controversial...if I was on a desert island and a single Hilary Clinton and a single Sarah Palin were on offer as a choice for a mate, well, I don't mind saying I'd happily ask a single Mrs. P to take off her glasses on a regular basis!
And the Secretary of State can keep her day job!
WHOOOOHOOOOOOO!!!!!

City, I don't believe in schizophrenia and neither do I.
Can someone give me their opinion on the other instructors changing their mind about the golfing machine and now saying the golfing machine has mistakes in it and is not correct? This is very disappointing for me. I have learned very much and the book has helped me tremendously. I don't claim to understand everything in the book but what I do understand has helped me.
Jerry I recommend you immediately change your game to reflect the fact the ball responds not to separation but to some point between maximum deformation and separation.
Had Homer known this back in his day I still dont think he would have changed the wording in the 1-L because it is of no use "practically" to the golfer on the tee.
Still waiting for the final word on Hinge Action.......you may be able to start Steering with impunity in the near future. TBD. Golf is about get way easier......
I have no horse in the race but for all the science I've seen touted it doesn't seem to refute that when I hinge differently (and I DO understand hinging and can execute it) I STILL get a lower straight and penetrating trajectory with HH, a higher and slight l-t-r traj with AH (easily offset with an address correction of the face as needed), and a very high traj with VH.
As much as I'd like to side with "unadulturated science" I don't understand what it tells me that I'm not already experiencing with HK's ingeniously simple hinge-action description. In fact I'd argue that HK's hinge description makes it much easier for any golfer to execute the motion rather than the golfer having to figure out how to move the face to achieve a set of numbers thru impact.

Those that teach the book well get wonderful results. Students hit straight shots with compression. I have seen a number of instructors demonstrate hinging and its different ball flight characteristics. So I guess this is an area that science may not have a handle on yet. Aiming at the inside aft quadrant of the ball seems to work. Tracing the plane line works for me. For the average student it appears that TGM can be trusted as it stands to improve your game. The Trackman data can be very helpful and information gleaned from it. High speed cameras can and should be used by instructors to help their students. New knowledge in biomechanics can also be used to improve instruction. Remember the goal is to educate your hands with the correct feels to hit the ball better. TGM instruction and principles certainly can accomplish that. The three essentials are alive and well

Right on David!
I can see science as very helpful to guys competing in long drive championships. They use their stuff a lot with Jamie Sadlowski to prove their points...
How many shots per round are you just trying to hit it as far as you can? If you want to control your ball around the course, play shots other than a driver where you need a certain distance, not just the longest you can, you better learn how to control your lag pressure. I haven't seen science help play the game of golf... Homer Kelley does.

I could be wrong. I have been before, and will be again.
I had no idea what the current heated debates were about, but I eventually found out...
I read the argument about the "angle hinging". It basically says that if the horizontal vector of the club head velocity is always aligned with the clubface normal vector and one neglects the effet of ball deformation, the result for a ball before low point would be a straight flight to the right of the baseiine (a push if we assume that the plane line and target line are aligned). Then conclusion is then that the clubface should close with respect to the path during the interval to produce a shot straight at the target.
I believe Homer would agree with that, because the "horizontal vector of the club head velocity is always aligned with the clubface normal vector" translates for me as "clubface square to the arc" and since Homer says the ball starts in good approximation in the direction of the clubface, he would say the ball start on a tangent at the circle at any point in that configuration...that is.. right for a ball before low point.
The problem I think is that the author has assumed that "angle hinging" is maintaining the clubface square to the arc, while Homer says "left hand square to the plane" (sorry I'm not familiar enough with the book to quote the exact sentence). However, that ignore any effect from the choice of grip and from the hooked face club design as discussed recently here http://www.lynnblakegolf.com/forum/thread7691.html 2-J-1 says the clubface should be closed at Impact Fix or else, for a square face, 7-10 says that one should have an Open-Open Target Line.
To summarize the author says that maintaning the clubface square to the arc would result in a push but that's not what angle hinging is for Homer.
A remark: 1-L with a perfectly in line arm and clubface intuitively reproduces the author expectation that angle hinging implies clubface square to the arc.
I don't know if I can put this in perspective or by doing so help anyone get closer to Homer Kelley's Hinge Action Concept, but focusing on "Path" is not about Hinge Action.
The Clubhead has a Center of Gravity. The COG Orbits and the Orbit outlines a Path. The "Clubface" (Inclined Striker) has a direct relationship to the COG, not a direct relationship to the Path. Often, Clubhead/Clubface/Path is used simultaneously but to fully appreciate the beauty of "Hinge Action" and it's function, these identities should be kept separate so that their interactions can be understood at the most basic Level. Oversimplification of their relationships has lead to much confusion and misplaced purpose.
The Striker can move around the COG by associating it with one of three distinct Planes. Horizontal, Vertical Or Angled.
Hinging is about how Swingers and Hitters have an inherent difference in the way the Face of the Clubhead moves about the COG. So, although Clubhead Travel from Impact to Follow-through will show a significant Clubface/Path alignment difference we're much more concerned with the affect on the Line of compression differences and the potential problems this creates.
Rotating about a Horizontal or Angled Axis create different "Compression" Vectors when a Ball is Struck. Although we can change the Plane of Rotation by "Holding" the Flat Left Wrist to one of three Basic Planes, there is an "Inherent" rotation for Hitters and Swingers. So, Hinging theory is also a "Warning" to Hitters: Be Aware of the effects of your Inherent Rotation and compensate as much as you need to.
There's no doubt in anyone's mind that a player can "Hold" the Flat Left Wrist Vertical to one of each of the three associated Basic Planes and thus produce some serious Ball Flight differences.
The Point I'm trying to make I think, is that the Inherent Hinging Differences for Swingers and Hitters is about how the Rotation of the Right Forearm about the Axis perpendicular to an Associated Plane affects the nature of the rotation of the Clubface about the COG of the Clubhead from Impact to Follow-Through, must be kept separate from the field application of Holding the Left Wrist Vertical to one of the three Associated Planes. One is cause and the Other is effect.
But, there remains no doubt that "Holding the Flat Left Wrist vertical to one of the Three Basic Planes will impart the same motion to the Clubface." But my warning and that of Homer Kelley's is that without you focused on Rotating the Face about the COG, you run the risk of all sorts of mishaps, especially "Bending the Plane Line" or inadvertently disrupting the 3 dimensional Orbit.
So Homer is making it clear that Hitters use Drive out and Single Wrist Action which inherently causes the Right Forearm to Rotate on an Axis Perpendicular to the Angled Plane, while Swingers using CF Throw-out and Standard Wrist Action which causes the Right Forearm/Hand to Paddlewheel about an Axis Vertical to the Horizontal Plane. All of this cause a Rotation about the Center of Gravity of the Clubhead with the Hinge located at the Left Shoulder.
The icing on the Cake, is to be able to artificially mimic that Axis rotation and increasing our repertoire of "Finesse". Zone three.
