George clearly ripped it left in his prime playing years… then later focused on a teaching career. I can only assume that he may have taught more of a swingers move to the average golfer figuring few would work as hard as he did to become a fine hitter.
His Bermuda video was certainly more relaxed looking going through impact than 15 years earlier, but it was far from a full on TGM style dump it out to right field move.
One might suggest a relaxing walk on the beach, but to do so, the legs are hardly relaxed, especially walking in sand.
We get used to a certain level of muscular tension, and any amount less than that could be perceived as a relaxed state.
To me George was absolutely viscous going through impact in his prime. A more relaxed version of that “to him” may have given the sensation of dead hands, and now conscious involvement, but I still think in Bermuda, he was pulling very hard against CF post impact. His torso wasn’t accelerating post impact to the degree it did in the 1960’s but it still was VERY good.
I think it would be interesting to see the difference between whether or not the left arm and shaft are allowed to move passively inline (from a DTL view) or if the angle of the shaft and left arm are preserved from P3 to P4, held firm by resisting forces applied through hand strength.
In your diagram it appears this would support cupping the left wrist at the top of the swing which would increase the angle.
Presently the calculations were done for passive wrists. But what you are looking for as comparison requires a rather more sophisticated 3D model to include roll of arms. Flailing acts as a velocity multiplier. Holding the arm/club angle for as long as possible maximizes this action and assures a clean hit. Also at some point in the downswing the club has to release to make contact with the ball.
Do you suppose this is why Homer completely ignored it in TGM? Possibly he couldn’t really wrap his head around it? even though it was used by many of the games finest strikers?
I agree that it does become more of a 3D imaging concept, and TGM seems mostly explained in 2D diagrams.
I think it is much easier to experience from the cockpit, than map it all out. I suppose Homer not being a great player, or certainly not having a swing that cut it left, held wristcock and fired with active hands, with a post impact accelerating pivot… left him not able to properly catalog it.
We, humans, like to generate concepts. However once established they often take on a life for themselves. They first are enlightening but subsequently they frequently act as a hindrance for further free thinking.
Isaac Newton’s great popularity, a real genius, also became a hindrance, not generally known. After his death, any new idea to be accepted by the Anglo Saxon scientific community as truly scientific had to have an equivalence using springs and masses. This clearly did not make it easy with the rather abstract new scientific ideas emerging, especially in continental Europe.
Hence more an idea/concept is heralded more one should be aware of its potential negative side effect. Such is the case for the concepts such as circle and plane, at the heart of TGM thinking. It first appears indeed to be very attractive but once self appointed ‘gurus’ take hold of it, it rapidly becomes a rigid type of religious affair, preventing to truly think golf in 3D as should be the case.
I have arbitrarily chosen the ball position to be opposite the central pivot. If you look at Figs 1, 2, 3 in the two linked posts you will notice that the behavior of the club up to and at impact is either very similar indeed or looking identical. One can therefore deduce, even if it is not specifically indicated, that the low point is indeed very similar for the various cases. However I will in a few days do a more precise analysis.
