Ten-and-In Putts Reading and Sinking Geoff Mangum The PuttingZone Four Skills of Putting — The Ten-and-In ZoneApril 27. 2015Putts outside 10 feet usually have less than a 50% probability of being one-putts.

On the PGA Tour, the average pro sinks 40% from ten feet in Tournament play. That leaves a 60% probability that these putts from ten feet are two-putts. The “average” pro distance where the pro is 50-50 is currently 8.2 feet.

But actually, the TOP golfers on Tour at ten feet do better than the average 40%, and the stats leader over a year can sink as high as almost 60% from ten feet. But the ten-foot mark is a useful demarcation of putts, so that inside ten feet putts are more likely one-putts than two-putts, while outside ten foot putts are more likely two-putts than one-putts.

Accordingly, a golfer wanting to spend time getting good at one-putting for either birdie with first putts on greens reached in regulation or for par-save one-putting after chipping close onto missed greens in regulation would be smart to focus on the “ten-and-in” range.

Not only are these the putts that in competition NEED to be one-putted more frequently than the competition, but longer putts are not as likely to be one-putted even with great skill, and improvement over the competition pays BIGGER DIVIDENDS as the putts get closer inside the “ten-and-in” range.

This latter point follows from how many putts a player actually faces in a round or in a year: half of all putts Tour players face in a year are inside 5 feet, and 65% of all putts players face in a year are inside ten feet. So working on the “inside 5 feet” range (50% of putts) is about 3 times more valuable than working in the “5 to 10 foot” range (15% of putts). And likewise, working in 1

the “ten-and-in” range (65% of all putts) is at least twice as valuable as working on putts outside ten feet (35%), especially since it’s not likely the skill can be improved a great deal outside ten feet and even if so, the number of putts one-putted from outside ten feet compared to the field is not a big number — nice but not all that significant.

The golfer then ought to be the MASTER in knowing all there is to know about putts in the “ten-and-in” range, with a second-level expertise in the “five-and-in” range.MASTERING THE KNOWLEDGEThe first thing to do is identify WHAT KNOWLEDGE one needs to learn.

The first type of knowledge is physics: How do the different factors that matter to breaking or straight putts — slope, green speed, distance, surface shape, elevation change, and ball pace — operate to determine curve, start line, aim target, and ball pace to sink these putts?

The second type of knowledge is greens: How are greens designed, built, maintained, and conditioned to result in certain typical or common patterns of the factors that matter to the putt — what slopes, slope directions, green speeds, distances, surface shapes, and elevation changes can be expected as common and frequent when playing a round of golf?

The third type of knowledge is human performance: What sorts of stroke setup and motion patterns are effective for line control and what sorts of setup and motion patterns and timing patterns are effective for pace control and how do these human performance process of perception and movement actually operate, so the golfer knows the how-to of skilled performance for line and distance?

EXECUTIVE SUMMARY

Putts inside 10 feet very frequently present with common features: slopes between 1% and 3%, green speed about Stimp 10’, surface flatness same from ball to hole. As a ballpark first read, these putts with a smart ball pace break 0.5” per foot of putt on 1% Slope and in multiples of this for 2%, 3%, and 4% Slope.

These putts also break 2.38 degrees off the baseline to the high side for all 1% Slope putts (any distance), 4.76 degrees for all 2% Slope putts, 7.14 degrees for all 3% Slope putts, and 9.52 degrees for all 4% Slope putts.

And for each slope there is a circle range within which all putts aim inside the hole: 1% Slope out to 4.25 feet; 2% Slope out to half that or 2.125 feet; 3% Slope out to 1/3rd that or 1.42 feet; and 4% Slope out to 1/4th that or 1.06 feet. And further out from these “all in” circles, there is an X for any Slope and Distance formed by crossing the arms of the X at the target spot above the hole with each arm grazing the edge of the hole, so that the vertical sections inside the X define uphill and downhill putts that are all aimed inside the hole.

These Xs also serve well for targeting where long lags end up, on or near the fall line inside the X so that the next putt is easy.

PuttingZone’s New Innovations

Geoff Mangum On reading putts with the four skills:

In the PuttingZone we teach math and physics for ballparking the read (more simple and accurate than APE) and then teach three instinctive visualizations with the golfer’s optimal, usual ball speed. These three movies accept the putting situation as it is without estimated numbers, and so yield a read that is more accurate and scientific than “calculated” aims using estimations of slope, green speed, distance, and slope flatness.

The three movies all agree on the imagined curve the ball will actually follow over slope and contour into the cup. And the three movies show the same start line at the beginning of the imagined curve. And the end of these start lines at the fall line above the cup all identify the same aim target. And these aim targets usually adjust and correct the estimated math calculated target with a minor adjustment.

Then the golfer is taught how to aim from behind the ball at the target, how to aim from beside the ball by following the aim of the putter face straight up across the green as far as the fall line, and how to sense the correctness of the aim with the body setup and stroke movement habit the same way a golfer aims a seven iron at a flag stick.

Then the golfer is taught how to stroke the ball exactly where the putter face is aimed.

And of course the golfer knows how to have focused action intentionality to the space at the hole for rolling the ball to and nicely into the cup or with pace that stops shortly past the hole, using natural tempo and the body’s instinctive sizing of the stroke for the distance, green speed, and any uphill or downhill.

The math is only used if the surface slope is the SAME from ball to hole, which means the same flatness, and not two or more different slopes or changing contour. If that is true (usually not for putts longer than about 10 feet), the method using estimated numbers is this:

Perceive the fall line or straight putt up thru the hole (as taught) and then estimate the slope using the eyes and the golfer’s trained familiarity with the look of usual slopes (no guessing ankles). Then aim this many inches from the center of the cup straight up the fall line:

Inches of break = Distance of ball from center of cup (feet) times Slope % / 2 (inches of break per foot).

For example, the math target for a 7-foot putt over 2% slope is:

7’ x 2%/2 = 7”.

Imagine a target (tee peg) in the green on the fall line above the cup 7” from the center of the cup. Aim there, and putt straight where aimed with the usual perfect pace.

A 4-foot putt over 3% slope aims

4’ x 3%/2 = 6”.

In general,

a 1% slope breaks 1/2” per foot;
a 2% slope breaks 1” per foot;
a 3% slope breaks 1.5” per foot; and
a 4% slope breaks 2” per foot.

This math is estimated based upon empirical testing of good ball speed on usual green speed (about stimp 9.5’ to 10’). If the speed is faster, just tip the math — stimp 11’ is tipped 10% more break than stimp 10’.

Then forget the math and read the green with instinctive prediction with a more precise assessment of the factors that matter for more accurate science than the math.

The three movies all use an imagined baseline straight from ball to center of cup (that divides the green neatly into a high side and a low side), and a length of line from the hole straight up the fall line — making a “corner” for the breaking putt that renders irrelevant all of the rest of the green outside this corner. With this corner in mind, imagine these three movies each with the same perfect ball speed the golfer actually putts with:

1. Imagine putting straight down the baseline at the center of the cup with perfect pace and then predict exactly where the ball curves below the baseline and crosses the fall line below the cup, before stopping within another 1-3 more rolls. The target is the same distance up the fall line.

2. Imagine a perfect-pace putt entering the cup from the high side of the “corner”, deciding exactly the final inch or so over the rim; then pretend a small car drove over the rim on this path into the cup and drive this car in reverse back along the predicted curve to the ball; once there, imagine the car’s headlights shine straight along a start line to a “target” spot on the fall line. This target will be the same as predicted in movie 1.

3. The third movie is a “feel” that starts by aiming down the baseline and imagining only perfect pace, knowing that the aim line is too low and the ball will quickly curve off the baseline to the low side. Then angle the putter face a little to the high side and check the body feeling — if the aim is still too low, the body will “feel a need to putt faster than perfect pace in order to keep the ball on the high side of the baseline all the way to the hole.” If you get this feeling, the aim is too low for perfect pace, so angle the putter face aim to a slightly higher start line and check the body feel again. If this line is still too low, the body feel of needing extra pace will still be present, but will be smaller of fainter. The golfer in this manner aims until the body feel signals that the aim is just high enough that no extra pace is required and perfect pace will for the first time keep the ball on the high side all the way to and into the cup. At this point, imagine headlights on the putter face shining straight along a start line at a spot on the fall line. Thus target will agree with movies 1 and 2.

My experience is that the instinctive movies will usually not be exactly the same as any math target but will only be a minor adjustment.

There is plenty more about teaching reading putts in the PuttingZone, but the above methods have been developed exclusively in the PuttingZone for the first time in golf history and are earlier than any other aiming-only gimmicks with the exception of the 1984 book by Colonel H.A. Templeton of Dallas Texas, who spent a year or more mapping green contours and experimenting with putts and green speed and slopes and computer programs snd aim charts, all explained in his 200-page book full of greens agronomy and ball-roll physics called Vector Putting: The Art and Science of Reading Greens and Computing Break.

So it’s not really true anymore that the best way to learn how to read greens is alone trying this and that on greens for years. There’s a lot to learn and know and use way beyond sticking fingers up in the air.er your text here...
