Most golfers are taught to read greens by choosing an Aim Point on the high side of the hole. The problem is that an Aim Point has no meaning without a defined speed. If speed changes, the correct line changes as well.
The Puttalyze System is built on three connected variables:
Aim Point – the ball's starting direction.
Distance Point – the energy delivered at impact, defined by where the ball would stop beyond the hole.
Target Speed – the ball's speed as it reaches the hole.
These variables cannot be separated.
The real driver of break is travel time. Gravity pulls the ball downhill every second it is rolling. A slower putt stays in motion longer, allowing gravity to create more lateral break. A faster putt reaches the hole sooner, reducing gravity's influence and producing a flatter trajectory.
Green speed also changes the required Aim Point. On fast greens (higher Stimp), the ball needs less initial energy, rolls longer, and therefore breaks more than on slower greens with the same slope.
The Fall Line—the steepest downhill direction through the hole—is the reference for every calculation. Sidehill putts experience the greatest sideways influence, while uphill and downhill putts are affected more along the direction of travel.
A scientific putting routine follows four steps:
Evaluate distance, slope, green speed and angle.
Determine Aim Point, Distance Point and Target Speed.
Align the putter to the calculated start line.
Deliver the correct amount of energy.
The Puttalyze System standardizes Target Speed at 3 rotations per second (3 rps) at the hole, creating an ideal balance between predictable roll and maximum capture width.
Common mistakes include believing there is one fixed Aim Point or assuming every miss is an aiming error. In reality, many low-side misses are speed errors. Two different speeds always require two different lines.
Key Takeaways
Gravity is constant.
Travel time determines break.
Speed dictates line.
Faster greens require wider Aim Points.
Uphill putts break less because they require more initial energy.
The Fall Line is the foundation of accurate green reading.
Elite putting begins when green reading changes from visual estimation to a scientific calculation that combines Aim Point, Distance Point and Target Speed into one integrated system.
