As usual, what I uncover most during research is discovering my own confusion.

I finished reading a Physics article on the subject because I wanted to find out what advantage(s) are gained by Sergio, Hogan and many more like them who form an acute angle between their Left Arms and Clubshafts at the Top of their Backswings. They seem to do so at the expense of a Level Right Wrist. This topic has emerged so much these past few days and I have this unsatisfying feeling that something has been missed. Dismissing one or other alignments as “not the best way” doesn’t explain why they do so. So rather than criticize them, I spent just a short time trying to uncover the mechanical advantage to this seemingly mechanical disadvantage.

I just recently discovered the word "Torque". I’ve heard the term before but I honestly have never had the need to understand the Physics of Torque. Torque is Maximum when the Force is at 90 degrees to the lever. And believe it or not, this led to Centrifugal Force which led to slings and Catapult engines and their design strategy. Bla, Bla, Bla.

But anyway, here goes first assumptions.

By decreasing the Angle between the Left Arm and Clubshaft at the Top of the Swing, they delay the Throwout Action (onset) of Centrifugal Force and gain more time to reach their maximum hand speed. So, the acute angle helps them achieve a Delayed Release and Max Hand Speed which may lead to higher Clubhead Speeds.

Anyway, it’s a thought. Can anyone (except Bucket) shed some light on the subject?
