Speed Changes Everything

February 20th, 2014 | AimPoint, Quintic Ball Roll, Tuition

by Mark Sweeney, Founder AimPoint Golf

I recently conducted the first of a series of planned studies with AimPoint instructor Jamie Donaldson, and Paul Hurrion and Jim Mackay of Quintic Consultancy to determine how differences in launch conditions in putting affect the outcome of the putt. The concept is simple–if I hit a putt with perfect line and start speed, but with varying amounts of skid, will it cause me to miss?

The Quintic Ball Roll system uses high speed cameras to measure a variety of factors including speed, roll and skid during the first 16 inches of a putt, yielding fascinating information about how different launch conditions effect the putt. Our goal was to better understand a player’s ability to control speed and distance, whether through normal variances or by changing launch conditions.

The data set we used was a series of 10 foot putts hit by a multiple winner on the European Tour who is ranked in the top 100 in World Rankings. He is know to have extremely good speed control and his variance is thought to be about as good as a human could control. What we found was that his initial launch speed only varied by 5%, but the ball speed 16 inches into the roll varied by 11%, due to differences in launch angle and skid. This equated to a difference of 0.4 mph of velocity between the fastest and the slowest putt.

The next obvious question is how much does 0.4 mph of speed change the outcome of the putt. We then used the AimPoint software to simulate 10 putts across different angles and slopes so we could see how many went in and how many missed (stimp 11). Given a perfect line and 0.4 mph variance in speed, how many putts would the player make? The images below show the results of what percentage of putts would still go in, based on gradient and angle (the red lines are misses):

Putts Across a 1% Slope

Putts Across a 2% Slope

Putts Across a 3% Slope

The results clearly show that as the slope gets steeper, the speed variance causes bigger misses. Keep in mind that this player has what is considered world-class speed control with only a 0.2 mph variance around his average. It also shows that smaller uphill angles are more forgiving of speed variances than cross-hill or downhill angles, something we have certainly seen while teaching.

From a strategic perspective, it should be obvious where we want to putt from and why. And from a performance perspective we learn that having consistent launch conditions can have a big effect on distance control. But we also learn that some natural variance in speed must be expected, and when condition get fast and steep, those downhill putts are dramatically harder to make than the uphillers. Putting is a game of percentages, be sure you know where the odds lay in your favor.

Covering all the Angles

After a particularly good putting display, 1991 Masters Champion Ian Woosnam was once quoted as saying that his performance on the greens was all down to an evening’s practice putting on his snooker table. Which gave me an idea. A perfectly true surface, no grain, no pitch marks…no excuses! What can the green baize teach us about putting? Let’s rack ’em up


By Dr Paul Hurrion



Before you can work on the finer points of your set-up and stroke, it’s vital that you have the ability to ‘see’ and relate to a perfectly straight line to the hole. So one of the very first things that I do with a new pupil is challenge his or her perception of a straight putt. And you’d be surprised at the results, even among tour players.

Cue the snooker table! As you see here, I have set up a simple test from 10 feet (you can do this yourself with a line of balls on a putting green or at home on the carpet). Placing the brown, blue, pink and black on their respective spots, I have lined up the cue-ball in balk, to create a dead straight line down the table. (When you practice this on a green, it’s a good idea to use a chalk line to give yourself a perfect line of reference. Indoors I use a builder’s laser – you can pick up both of these products cheaply at the hardware store.) With the straight line of balls in place, the challenge is to address the cue ball and take ‘dead aim’ at the nearest ball (i.e. brown), just as if I were aiming to strike it face on. I focus on squaring the putter-face to the brown ball and, when satisfied with my set-up, I look up to focus on the next ball, the blue. What do I see? Does the line of balls still appear straight? Well, not really… and I feel the need to adjust my putter alignment to the blue ball. Moving my focus further down the table, to the pink and black balls, do I feel I should realign my putter? Well yes… but I know all the balls are aligned correctly? What sense does it make to feel the need to align the clubface differently for straight putts of 2 feet (to the brown ball), 5ft (blue), 7ft (pink) and 9ft (black) all down the same line? What is happening?

The answer is that, according to their position relative to the line we are looking down, our eyes provide differing information to the brain as we turn our heads and focus further away. The length of the snooker table, with the use of the brown, blue, pink and black spots, enables me to place the balls in a perfectly straight line.

All you snooker players out there know that it’s pretty easy to see a straight line when you are in position, eyes low to the table. But what happens when you stand up to a putting posture, taking your position to the side of the ball? And what happens when you then swivel your head to scan the line to the hole? Do the balls still appear in a straight line?!

The best putters in the world eliminate unnecessary movement and hone a stroke that is built around the stability of a consistent platform. Key to achieving that is a stable pelvis – and improving that alone will make you a better putter the next time out.

Putting represents half the strokes played in the average round of par golf and is, in many ways, a miniature version of the full swing – yet, perplexingly, it remains the area of the game least taught, least seriously practised and, perhaps, least understood.

The majority of coaching features and videos, manuals and textbooks suggest ‘feel’ as the key to success, along with ‘a good technique.’ However, thinking logically, a good technique must surely come first in order to create the consistent platform necessary to replicate the stroke that enables you to develop the ‘feel’ to hole putts. So, what factors contribute to a good technique? Strength may not spring to mind but I am of the firm belief that putting is a strength exercise. It is strength which gives you a stable posture and balanced pivot point – essential to the putter being returned consistently to impact from address.

Also, it is often advised by golf teachers that it is best to stand comfortably at address and relaxed over the ball prior to hitting the putt. However, it has been my experience that ‘comfortable’ does not necessarily translate into well-balanced and (potentially) creates an individual style of putting which often encourages (and indeed requires) a degree of manipulation during the stroke.

I believe one of the fundamentals to good putting is a strong, balanced set-up, and over the following pages I will introduce three specific drills designed to help you improve that quality in your own game. They will help you create that sound base for a consistent strike (and that same sound base will help the rest of your game, too).

At Quintic, we recently carried out research to study the set-up position of 30 elite PGA professional golfers and 30 amateur golfers (handicaps ranging from +3 to 9), all of whom were filmed whilst attempting the same level 20-foot putt on a surface with a stimp reading of 12. All 60 performed their regular putting action with their own putters whilst standing on an RSscan Footscan pressure measuring platform. The results were interesting. We found that there was a difference between the amateur and professional groups in set-up; the weight distribution of the amateurs was approximately 60:40 (in favour of the right side for right handed golfers), whilst the professionals were much closer to 50:50 at set-up.

There was also a trend to suggest that the wider the stance, the smaller the centre of pressure movement (i.e. sway) during the stroke. And although there was no appreciable difference in stance width between the two groups of players, there was a difference in the amount of sway with significantly more movement seen in the amateurs. As you will appreciate, the more (lateral) body movement, the more the likelihood of inconsistency in the path and tempo of the putting stroke – factors that contribute to inconsistency at impact and a loss of feel.

So, as ever in this game, the key is to get yourself correctly positioned at the set-up.

Let’s get to work.

Padraig wins PGA Gland Slam…

October 25th, 2012 | Padraig Harrington, PGA European Tour Golfers, PGA Tour

Padraig Harrington celebrated a return to winning form in the Anniversary 30th PGA Grand Slam of Golf in Bermuda at the Port Royal Golf Course, with victory over US Open champion Webb Simpson, Masters champion Bubba Watson and defending champion Keegan Bradley.

Harrington, shot a 67 on the second day to his opening 66 for a winning 36-hole nine under par aggregate of 133 – one ahead of Simpson, who shot a best of the day 65, and six in front of Watson (71) and Bradley (67).

Harrington, one of only 12 players in 2012 to make the halfway cut in all four Major Championships which included tying fourth and eighth in the US Open and Masters Tournament respectively, only received his call-up last Saturday as a late-replacement for injured Open Champion Ernie Els – but the 6,500 mile round journey enabled him to become only the second European golfer to win the title following Ian Woosnam’s success in 1991.

“It feels really good. I have not won in a while and it would be a nice habit to get back into. When it happens, you’ve got to enjoy it and we’ll be doing that tonight.

“I’m playing really good golf. There is some good stuff in my game right now; and there’s other stuff I need to tidy-up. I have realised with experience that wins do not come around as often as you would like. But I believe I’m going into a nice period in my career.

Congratulations, good to see you back in the winners circle!  Need to work on your cricket batting technique though…

Green reading is a fascinating and yet sometimes frustrating concept to master, trying to visualise break and speed, the effects of grain, wind and the occasional spike mark – is it any wonder that at times putting becomes nothing more than a case of hit and hope? Learning to recognise the true line of a breaking putt is the first step to building up your confidence – and this impromtu beach lesson can help…

One of my keys to putting is to understand the difference between a good putt and a poor putt. You can misread a putt, pull it and hole the putt – does that make you a good putter?  Hey, you got lucky… but two wrongs don’t always make a right. This style of putting would perhaps at best be streaky, but not one that will deliver a consistent, repeatable stroke. I find the majority of amateurs and even seasoned professionals tenoctd to underand through the course of this article I’m going to explain why. And how about this for a prop : using the golden sands of Constantine Bay here at Gi HQ in Cornwall, I’m going to provide a graphic illustration that will enhance your ability to visualise the true break.

A Rolling Brief – Putter Face vs Path

July 25th, 2012 | Golf International, Quintic Ball Roll, Tuition

“Quantifying the relative and conflicting effects of putter path and face angle on the direction and motion of the golf ball” – that was our goal in producing a research document based on our own extensive testing.

The putter: the most used club in the bag but the most overlooked part of the average golfer’s practice. Golfers around the world are using the technology available in today’s market to help analyse and improve their golf swing. Technology is transforming teaching and club-fitting, offering golfers three-dimensional, frame-by-frame swing analysis, high-speed video and precise spin rates and launch angles that apply to the golf ball after impact. However, when it comes to putting, rather than analysing what our putting stroke and the ball are doing in detail, we simply opt to buy another putter with little more than hope that it will truly improve our putting performance.

Factors such as alignment of the putter face, path of the putter, launch angle, speed, impact location, grip pressure, forward or backwards rotation, hook or cut spin, grain, spike marks, slope and even wind can play a significant part in the outcome of a putt.

The vital question we like to ask our players is simple: “Do you know the difference between a good putt and a poor putt?” Without feedback on the launch conditions of each putt, is it possible to begin to answer this question?
