2.16 Dynamic bar charts
The dynamics 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 4.5.
Backswing Rhythm
Backswing rhythm describes the ratio of backswing time to impact time.
Backswing time should be approximately double as compared with impact
time (Tour average 2.1).
• Fast Rhythm: For this player the Rhythm is slightly smaller which means
that he is more aggressive in the backswing. Generally players with a
faster Rhythm tend to less monitor details of their putting stroke.
• Slow Rhythm: High numbers for backswing rhythm identify players with a
cautious backswing who tend to more control the technique during the
stroke.
Impact timing
The "Impact timing" parameter indicates at which point during the entire
forward swing you hit the ball. Impact timing describes the ratio of impact
time to forward swing time. Hitting the ball early in the stroke ensures
impact before maximum speed, and hitting before maximum speed per
definition means accelerating through impact.
For beginners impact timing is about 0.5 or even higher because the ball is
in the center of their stroke. For professional players the timing comes down
to about 0.35-0.4. This timing guarantees a positive acceleration through
the ball because the maximum speed is reached after impact. Average
impact timing of the Tour Pros is about 0.39 which means the hit the ball
after 39% of forward swing time.
Speed at impact
The "Speed at impact" parameter shows the speed of the putter face exactly
at impact. High consistency of impact speed is most important for distance
control of the putt. Inconsistent impact speed can also be a consequence of
poor timing. In addition, speed at impact very often correlates directly with
the length of the backswing.
