Pecky...
With all due respect Pecky...
You couldn't be more wrong.
There are multitude of physical reasons why one golfer's arm is more bent at the top than another.
For example, Harry Vardon bent his arm more than Bobby Jones, although they both did plenty.
That tweed coat didn't help.
Mike Finney, 6'0" 155, and Brian Manzella 5'9" 200, are built very different, and trust me, after my 97% rotator cuff tear was PERFECTLY repaired by Mike's brother—Tim Finney, New Orleans Saints Team Doctor—my arm bends more than it did before.
But, you see, Pecky, there IS THE EXACT SAME ABOUT OF SLACK—OR NO SLACK—IN MY SWING NOW (MORE BENT) AS THERE WAS BEFORE (LESS BENT).
When the first batch of research was done for "left arm bend" at the top, for a driver, in the early 80's, the average bend on the PGA TOUR was 30°!
I teach some folks to bend their arm on purpose—for effect.
Some folks need more stretch.
You are in the right place to learn—and it is clear, that in this area, there is a lot to take place.
I'll do my best to help.
START HERE: Slack vs. bend is NOT a 1:1 ratio for ANYONE, but differs from golfer to golfer.
