"Consistency in putting stems from creating consistently good starting positions
– I call these constants and they are:
(1) Constant Eye Position,
(2) Constant Hand Position and
(3) Constant Ball Position.
If you start in exactly the same position every time then you will develop a putting
stroke that repeats. The Optimizer prism consistently sets you in the correct position
for executing the perfect putting stroke, every time.” [Peter Cowen]
