SAM Puttlab Analysis Reports

Putter Head Rotation
This graph shows the putter face angle at different positions in the forward swing: At the start of the forward swing (right), at impact (middle) and at the end (left) of forward swing. The red lines indicate the deviation of the putter angles from the square alignment.

Under the putter face pictures the corresponding angles are shown. In this case the putter face is open 2.0 degrees at start of forward swing. (Because the putter face was closed 0.7 degrees at address, it was opened 2.7 degrees during the back swing.)

At impact the putter face is open 1.8 degrees. The value above the blue arrow shows the corresponding closing of the putter face to impact of 0.2 degrees. From impact to end the club face is closed another 5.5 degrees and is then 3.7 degrees closed at the end of forward swing.

In the middle of the graph the face rotation for a fixed area of +/- 10 cm before and after impact is shown. The rotation inside of this fixed area is independent of the length of the putter path and allows to directly compare the rotation of putts with different path lengths. In this case the rotation inside of 10 cm before impact amounts to 0.0 degrees and the rotation inside of 10 cm after impact amounts to 0.7 degrees.

The two bars on the right side of the graph show the Score rating for the rotation at impact as well as the Consistency over the different putts. This player shows a rotation of 0.7 degrees inside of an area of +/- 10 cm around impact. The preferred amount of rotation as measured on the Tour inside of this range is about 1 to 3 degrees. The score level of 97% is very high and corresponds to a rate of rotation at impact of 6.6 °/s. The consistency of rotation around impact is average to good at 74%.
