Clockface Putts: A Baseline Approach describes a simple and effective mathematical model for analyzing putts on uneven golf greens. It uses the analogy of a clock face with the hole at the center to quantify the slope of the surface and its impact on ball movement.


Key Elements of the Model:


1. Fall Line and Slope:


- The fall line is the direction of the steepest downhill slope and corresponds to the 12-6 axis.


- The slope is expressed as a percentage of the gradient along this line.


2. Quadrants and Baselines:


- The surface is divided into four quadrants, bordered by the fall line (12-6) and the 9-3 axis.


- Each "hour" on the clock represents a baseline running from the ball to the hole.


3. Baseline Slope Values:


Using the cosine of the angle between the baseline and the:


- 9-3 axis, approximate slope values are determined


- 9-3 Axis (Sidehill): 100% of the fall line slope


- 2, 4, 8, 10 o’clock: 87% of the fall line slope


- 1, 5, 7, 11 o’clock: 50% of the fall line slope


- 12-6 Axis: 0% slope


4. Symmetry and Training Focus:


- Putts on symmetrical positions (e.g., 4 and 10 o’clock) have identical slope values.


- Practicing putts at 4 and 5 o’clock allows a player to understand patterns for many other putts.




Advantages of the Clockface Model:


Visual Representation: The model provides an intuitive way to visualize the slope around the hole.


Easy Break Estimation: Players can estimate the slope and break based on the ball's position on the clock face.


Efficient Training: Symmetry patterns allow players to gain maximum insight into various putts with minimal effort.


This method offers golfers a practical way to improve their putting analysis and train for breaks effectively.
