2.10 Side View bar charts
The side view bar charts provide information on each single putt. The
colored stripes within the bars represent the different putts. The more
closely grouped the stripes are, the more consistent the performance is. The
structure of the graph is identical to the "Alignment bar chart" in chapter
2.4.
The parameter "Shaft at impact" provides information on the shaft angle at
impact. This parameter directly corresponds to adding loft or delofting the
putter face at impact. For this player the shaft is almost neutral at impact.
As consequence the net loft if the putter to the ball is the static loft plus 0.1
degrees. If the putter has about 3 degrees loft on the face, then the
resulting net loft at impact will be 3.1 degrees.
The "Height at impact" parameter indicates the height of the putter above
ground while hitting the ball. This player hits the ball with a height of 8.1
mm above the ground. For hitting the ball in the vertical sweet spot a height
of about 8-10 mm is perfect. The hit distance on the putter face is shown in
the Impact spot graph in chapter 2.6.
The "Rise angle" parameter shows the angle of the putter path against the
horizontal ground at impact. For this player the rise angle is 2.2 degrees
upwards, which is little less than the perfect range of 3 to 4 degrees. A
positive rise angle will give the ball some forward spin and a better roll. The
skidding phase will also be reduced.
There is an inter-dependence between rise angle and loft at impact. The
more rise angle at impact is found the less loft at impact is needed to
properly lift the ball from the ground. High speed video suggests that you
should avoid backspin and skidding of the ball for proper roll. On a stimp 9-
10 we recommend only 1 degree net loft but a rise angle of 3-4 degrees
upwards, which will properly launch the ball and will impart immediate
topspin to the ball.
