In putting, the actual hole is rarely ever the target!
Using an x/y coordinate system, the
idea is to slide the actual hole on the axis to identify and putt at a projected
How much you slide the projected target hole up/down/left/right on either
axis is dependent upon how the green is sloped, e.g.,
The ball is shown at the bottom of the diagrams next to the image of
The actual hole (white) is located at the intersection of the x/y axis
The Pelz Constant projected hole (blue) is
17" behind the actual hole.
The delta y projected hole (purple) is
adjusted distance on the y
axis depending on the uphill or downhill slope of the putt.
The delta x projected hole (red) becomes the
target hole and is
located an adjusted distance from the x axis depending on the
left-to right or right-to-left break of the putt.
The red line becomes the aim line and in
effect the putt becomes a
straight putt. Farnsworth strongly recommends aligning the ball's logo to
this red line.
The green line is the actual path the ball
will travel when struck at the correct
speed on its way into the hole.
