Andy,

Love the graphic!  I have a couple friends that seem like they are going through all of these "thoughts" on every shot, only it takes them much longer that 1.5 seconds.  I try not to play too many rounds with them during the season.

Like you, I like to keep my swing thoughts to a minimum.  I like to focus on tempo alone.  If my tempo is good, everything else falls into place.

I know people who have those thoughts running through their heads.  For me, less is more.  The less I'm thinking about during a swing, the better.  I try to pick one, maybe two things to focus on and that's it.  Any more and it'll do more harm than good.

My main swing key is to have a balance finish on my swing.When I concentrate on the finish position my tempo is good and I know I have accelerated through the ball .

As I started playing golf, I had many of these thoughts in my mind, but I recognized that my brain was to slow to deliver and check all those thoughts in queue and so after a controlled backswing the rest of the swing was randomized. Today on the course I try to think on turning my shoulders and getting a nice smooth tempo. That's all...
