Part 2
The Podcast focuses on optimizing putting in golf and explains two key aspects: the speed of the ball when it rolls into the hole and determining the fall line. The podcast describes various methods to identify the fall line, such as estimating the slope, walking around the hole, finding the highest and lowest points, visualizing water flow, and even performing push-ups. Additionally, it introduces the use of the Puttalyze app to assist in analyzing the fall line and simulating ball movement.
The ball's speed when it reaches the hole is crucial for a successful putt. Ideally, the ball should reach the hole at about 1 mph (around 3 revolutions per second or 0.45 m/s). This speed optimizes the so-called effective hole size and the minimum speed required to maintain a stable ball path. The effective hole size refers to the area in which the ball can still fall into the hole, even if it doesn't hit the exact center.
It is important that the ball, regardless of the distance to the hole, always has the same speed when reaching the hole. The reason is simple: only when the ball consistently reaches the hole with the correct speed can you start reading the green and understanding how much break the ball will have under different green speeds.
The Puttalyze app can help optimize the speed of your putt. It has a built-in slope meter that measures the slope of the green and the angle of the fall line relative to the ball-hole line. The graphical display shows the simulated putt path, target point, and distance point. The app's concept of corrected length takes into account various parameters such as green speed, slope, and angle to calculate how long a putt on a flat surface would need to be if it were hit with the same initial speed required to cover a certain length under the given slope and green speed conditions.
