You are effectively combining the wedge this way (arms pushing away) and turning the torso that way and when you do both at the same time, blended together with good timing you’re making an on-plane takeaway. That was the big light bulb and it expanded after that.
I didn’t quite believe it at first it was I was so excited I thought wow this is this explains a lot and I instantly got the ramifications for the rest of the golf swing particularly through impact:
- Why did I struggle with flipping
- Why did I struggle with disconnected arms
I thought you were supposed to move your arms with your arm muscles across the chest but I also knew that you could do it too much too early but I was still trying to do this sort of moderate disconnection of the arms. I didn’t quite understand that piece, I didn’t understand what Hogan was talking about so (when I finally cottoned on) it just set off a number of huge supernova-sized light bulbs for me so I was pretty excited about it.
It was the beginning of my journey to explore in-depth what that Arm swing illusion is all about and what several related illusions that support the arm swing illusion were all about. I was so excited I literally didn’t sleep for two nights.
I was taking notes, looking at video, reading books going back and look at my notes from the past, and notes in the margins of books I read. I recall the interview with Bob Bush who was the head of the team of Design at iron Byron talking about how the most shocking discovery was the RPM speed from here to just after impact of the shoulder girdle the arms and the clubhead were identical in the horizontal dimension. I finally understood what this meant.
I instantly got the propeller tip of the propeller hub that rpm mph illusion. I got the related lever illusion, how a small arc small degree arc of rotation at the pivot and the core of your body makes the clubhead move several feet. That came to me too.
These light bulbs were going off like supernovas in my mind. As a lifelong amateur scientist, I know that you’re supposed to try to disprove your hypotheses to see if they can take the heat and withstand more critical analysis. So, I looked at the arm swing illusion from a lot of different ways to see if I could disprove it. I focused a lot on videotape of professional swings and while there were some people on Tour who were violating the arm Swing illusion to some degree, they would have to make compensations to their swing in order to make good contact.
But with the modern swing, the ones where the club is moving on the original plane from you know from here to here and then raising up to a higher plane more vertical plane but the plane angle staying the same throughout the swing.
The more efficient looking swings you know, players like:
- Justin Rose
- Billy Horschel
- Jason Day
- Adam Scott
- Martin Kaymer
The ones that had really pretty looking swings, I sort of got what they were doing right and they were actually matching what my research was showing about the illusion even more than some of the older great ball strikers from earlier eras.
So, it held up. I tried to disprove it and it held up.
