#685 The Science of the Perfect Read: Why Calculation Beats Estimation

Reading a green is not guesswork—it is physics. Every putt is influenced by distance, slope, green speed, fall line, friction, and gravity. Understanding how these variables interact creates more consistent green reading.

As the ball rolls, friction reduces its speed while gravity increasingly influences its direction. The longer the ball rolls, the more time gravity has to create break.

The Puttalyze Physics Engine uses these principles to calculate the expected ball trajectory.

Accurate green reading requires five key measurements:

Green Speed (Stimpmeter)

Slope Percentage

Putting Distance…
