AimPoint and Green-Book Slope Data
A GPS number told you 147. That is yardage. A StrackaLine greens guide tells you the slope percent AimPoint is asking your feet to feel.
They are complements, not competitors. AimPoint and Kenyon-style reads tell you what to do with a slope percent. The greens guide is the actual percent on this green — laser-scanned topographic dual-view, printed at USGA scale. Pair them.
The method is not the map
AimPoint is a green-reading method. Phil Kenyon’s two-thirds formula is another way to think about where the ball should be. Neither one is a surveyed drawing of the putting surface under your ball.
A StrackaLine greens guide is that drawing. It shows slope in percent. It does not pick your line. You do. How to Read a Green Book.
What AimPoint is asking your feet to call
AimPoint was developed by Mark Sweeney. AimPoint dates the work to 2003. The Express read most golfers see on television uses your feet, then your fingers.
You straddle the line, feel which way the surface tilts, and assign that tilt a slope percent — typically 1 through 5. From behind the ball, you hold up that many fingers against the hole. That is the aim.
Golf.com walked through that sequence with Adam Scott (Zephyr Melton, 24 February 2025). On that page, Golf.com names Collin Morikawa, Viktor Hovland, Justin Rose, and Adam Scott among players who have adopted the method. MyGolfSpy’s explainer (Brittany Olizarowicz, 21 November 2024) is the same unit: feet estimate percent, each finger is about 1% of slope.
Learn AimPoint from AimPoint. The only way they teach it is through an AimPoint certified instructor (aimpointgolf.com). Stracka Golf is not that school, not a partner, and not “AimPoint official.”
What Kenyon is asking you to see
Golf Digest published Kenyon’s two-thirds formula (Luke Kerr-Dineen, 26 March 2026; the live slug spells “keynon”). Golf Digest reshared that piece on X on 1 September 2026, 9:00 p.m. PT (status 2094998752561963051).
Kenyon’s point: amateurs under-read because they think the ball goes straight and then breaks. It curves the whole way, more as it slows in the last third. His formula: pick where you want the ball two-thirds of the way to the hole, then double that distance from the hole. That is the start line.
That formula is Kenyon’s, not ours. We are not reprinting his drill as a Stracka method.
In the same Digest family (Kenyon, 19 March 2026), he splits green-readers into two buckets. Justin Rose and Tommy Fleetwood use AimPoint to measure how much a putt breaks. Russell Henley and Scottie Scheffler read more from address. He says pick a method and stay consistent.
Both buckets still sit on a slope percent. The book is how you see that percent on this green before you walk in.
What the greens guide actually prints
Dual-view topographic slope in percent, from a laser scan of the putting surface. A 1-yard / 5-yard grid so you can locate the ball and the hole. Hazards and sprinkler heads so you can rotate the page until it matches the ground.
Percent is rise over run. A 2% area is steeper than a 1% area. That is the same unit AimPoint is asking your feet to call. How to Read Green Heat Maps unpacks fall line, high ground, and low ground.
The book does not draw a recommended line from your ball. Rule 4.3 does not allow a map or a device to produce a line of play based on ball location. Scale is no larger than 3/8 inch to 5 yards. Paper is no larger than 4 1/4 × 7 inches. StrackaLine currently only ships the USGA legal version. What’s Legal? — USGA Rules.
How to pair them on a green
- Open the hole on the way to the green. Orient the page. Find the ball and the hole on the grid.
- Read the printed slope percent on the ground the ball will travel — not only the number nearest the cup.
- If you use AimPoint, that printed percent is the number your feet are trying to feel. Use it to calibrate, then make the read you were taught.
- If you use Kenyon’s two-thirds, the percent and the fall line tell you how much the last third should move. You still pick the spot and the start line.
- Hit the putt. The map showed the surface. You chose the aim.
A GPS watch did not replace a yardage book. It gave you a number you could trust, then you still had to hit the shot. Same split here.
What this page is not
This is not an AimPoint clinic. It is not a Kenyon lesson. It is not a partnership, endorsement, certification, or “official” page. Stracka Golf maps greens. AimPoint and Kenyon teach how to use a slope number. If you want the method, take their class. If you want the number on this green, order the book.

FAQ
Does Stracka partner with AimPoint or Phil Kenyon?
No. This page explains why a slope method and a slope map work together. It is not an endorsement either way.
Does the book replace AimPoint?
No. The book is the percent on this green. AimPoint is one way to use a percent.
Does the book tell me where to aim?
No. It shows dual-view topographic slope in percent and a grid. You pick the aim.
Is a StrackaLine greens guide legal in a tournament?
Yes, the version that ships is the USGA legal version. What’s Legal? — USGA Rules.
Where do I learn AimPoint itself?
From an AimPoint certified instructor. Start at aimpointgolf.com.
