2.12 Rotation Graphs
Rotation graph: The graph on the left shows the rotation over time for
each forward swing. The rotation graph also corresponds to the putter face
angles as shown in 2.11.
• At the beginning of the forward swing (beginning of the curve at the left
side) the putter face is about 6.8 degrees open.
• The impact is indicated by the small vertical stripes. The horizontal axis
corresponds exactly to the putting line. The graph shows that the ball is
hit with a slightly open putter face.
• At the end of the forward swing the putter face is about 6.7 degrees
closed (right end of graphs).
For this player the course of rotation is smoothly running from open face at
impact to a closed face at end of forward swing. For natural and smooth
rotation the rotation will always be symmetric to impact (stripes).
Rate of rotation graph: On the right side the corresponding rate of
rotation change (velocity of rotation) over time is displayed. The rate of
rotation graph displays the change of putter face angle over time.
Irregularities in putter face change are magnified in the velocity data and
correspond to peaks in the putter face velocity curve. For this player you can
identify a minimum re-opening of the face directly after impact through a
positive peak in the velocity curve. This "re-opening" can either be a
consequence of hitting the ball off-center at the toe (see 2.6) or can show
the tendency of the player to interrupt the natural rotation of the face and to
keep the face more square through impact.
A natural and continuous putter face rotation always shows a smooth and
flat rate of rotation curve and corresponds to high consistency ratings.
Inconsistencies of the putter face around impact correspond to the lower
consistency ratings in 2.11.
