I find it very easy to "see" golf through geometric shapes. I find it personally impossible to "see" golf through numbers, however, we are here to learn so I will pass this information on. The information comes from DV PUTT, a machine which measures a number of different elements of the stroke. Mike Shannon and I have had ours for about 2 years and here are the findings.

THE AVERAGE TOUR PLAYER
At address the alignment of the face is less than 1/2 a degree open or closed.

At impact the alignment of the face is less than 1/2 a degree open or closed.

During the impact interval the putter head is moving from 1 to 3 degrees in to out.

There putter faces are square to the arc or even slightly closed. This means they are using an angled hinge or angled/toward horizontal.

The measurement of their arc ranges from 50 to 100. The putting arc is is 107 on the DV PUTT which is the reason tour players like it. They have a tendency to move in too big an arc.

Their backstroke length and their through stroke length is BALANCED. No short back, long through stuff.
