There’s lots of talk about TrackMan club head speed readings, especially on the PGA Tour with Tiger Woods at the moment.

What happens with a club head at impact and how TrackMan is recording the movement of that club head is all physics. In this video, I explain a little bit about how TrackMan gathers information and the physics behind measuring objects moving in 3D space.

    Nice video. So do we expect ball speed readings are more accurate? And why does clubhead speed even matter? Isn’t it all about ball launch characteristics? Also, what factor does clubface rotation play in the transfer of energy to the ball? Isn’t the clubface speed at impact increased by rotation? I get that your point is the variation in clubhead speed measurements and that is well taken.

    Would a machine like the foresight be more accurate then due to its position?

    Trackman doesn’t match up to my high standards for launch monitor data and I reject it because it’s just not good enough for me. End of story.

    This explanation shows why you can get smash factors in excess of 1.50 but not quite what is happening when it reads the head fast, it has to do more with the mass of the head and how many different major mass parts there are in the head and why it mis-reads club head data from time to time.

Opinion & Analysis

How often should you actually get “Up-and-Down” based on your handicap?

Published

on

‘Up and Downs’ have long been the accepted measure of skill in the short game. The chart below shows average performance in this area for the PGA Tour and an array of handicap levels. How do you fit in?

A few points of definition: The above refers to short game shots around the green, other than from the sand. [Stay tuned: sand shots will be my next article.] I consider the short game to be all shots from within 50 yards of the hole. This distance was a topic of debate 30 years ago when I was developing my golf analysis program. I was fortunate to be working with Golf Digest Golf Schools and some of the top instructors were good enough to embrace the better form of game analysis that I was creating. In particular, I owe a great deal to Chuck Cook, Jack Lumpkin and Hank Johnson. Their help and encouragement in my early stages gave me a much needed boost of momentum. Little did we know that what I then called “Strokes Lost and Saved” would ultimately become the accepted standard of analysis on the PGA Tour — now know as “Strokes Gained.” Anyway, we agreed that 50 yards was the right distance range for the short game for two reasons:

  1. It represented the short game for virtually every handicap level, men and women.
  2. It was a short enough distance that it didn’t need to be sliced even further.

That said, I do NOT believe that “Up and Downs” are an appropriate or accurate measure of short game skill for two reasons:

  1. It represents the combination of two skills: Short Game and Putting.
  2. It ignores the ERRORS or shots that actually miss the green.

In my 30+ years of studying performance at all skill levels, I have found that it is the FREQUENCY and SEVERITY of bad shots (errors) that do more to influence a player’s scoring level than do all the good shots. Accordingly, I built the ability to capture data on the common errors in the game into ShotByShot.com.

The true measure of a player’s short game skill is their Strokes Gained in that facet. BUT, that is simply a number — a positive number is good and a negative number, not so much. But how then to best display the skill that is associated with the Strokes Gained number? I believe the combination of three stats to be the correct way to display short game skill:

  • Average putting distance, when the green is successfully hit.
  • Percent shots hit to within 5 feet of the hole
  • Percent errors, or shots that miss the putting surface.

Where does your game fall in these two important categories?

Note, that the two lines cross at about a 16 handicap. That is actually a better than average golfer yet for every Chip/Pitch shot that they successfully get to within 5 feet of the hole, they are also chunking or sculling one and missing the green altogether. Work to dramatically reduce the errors and that 16 will drop to 12 or 13?

You might ask: How can the PGA Tour make more errors than the scratch golfer? Good question! I have two explanations:

  1. They really are that good! Regardless of the relative difficulty of the shot, Tour players will go for it. They have the confidence that when they miss they will get the next up and down. At the same time, the amateur that has reached the lofty level of Scratch has generally done so thru rigorous consistency and the avoidance of errors. At the low handicap levels, a bogey can be acceptable but a mistake that results in a double is NOT.
  2. The tour Shotlink data considers the fringe of the green to be a miss whereas I recommend that players count the fringe as a green hit and a putting opportunity. Your long game has been efficient enough to get there and should be rewarded with the GIR. At the same time, to count the shot from the fringe as a short game shot will unfairly reward your short game skill for what was actually a putt.

That reminds me again of my very early days when Chuck Cook said to me: “Pete, Tour players don’t make errors in the short game!”  See Chuck, I was right, they do! For a Complete Strokes Gained Analysis of your game, log on to: ShotByShot.com.

Opinion & Analysis

Think Carnoustie’s hard? Try winning a title on it playing golf with one arm

Published

on

When things get challenging during the 147th Open this week on the Championship Course at Carnoustie Golf Links in Scotland, the players would do well to think of Mike Benning–specifically the fortitude he channeled into success at the venerable venue.

Benning grew up with golf at Congressional while his father, Bob, was head professional at the iconic country club in Bethesda, Md. Due to a rare form of cancer, Benning, who was already a top junior in the Washington, D.C. area, lost his left arm below the elbow to amputation at age 14.

Rather than let that stop him from playing, he learned to adapt. So much so that he won back-to-back Society of One-Armed Golfers world championships in 1993-94. The first win came at Seaford Golf Course in Sussex, England, in 1993. Benning defended his title at Carnoustie in 1994, the 56th and 57th renditions of the annual event, which began in the 1930s.

Benning was low medalist in stroke play at Seaford, shooting 80-81-161. With the top 16 finishers advancing to match play, Benning won four matches in two days to become champion. He went to Carnoustie the next year full of confidence but couldn’t find the form initially that carried him at Seaford, qualifying 10th in medal play.

“My game wasn’t on, and the course was brawny and fast,” Benning said this week from his home in Scituate, Mass. “The course was so dry it was grey, and it was windy. That makes Carnoustie very difficult, even more challenging than normal. I had a difficult draw in match play, but I found my game when it mattered most, and only one of my matches went to the 18th hole.”

In the championship match, Benning defeated Scotsman Brian Crombie of Dundee, a 25-minute drive from Carnoustie.

“He had about 50 friends and family members rooting him on, the crowd was definitely behind him,” Benning recalled. “But I had a couple Americans following me. One was Mike Gibson, who now works for Titleist. He came out wearing a pair of red plus fours and an American flag shirt. He and Mark Frace really propped me up. I remember having a big decision on the 10th hole – whether to try and get a 3-wood over the burn – so I turned and looked at those guys behind me, and they encouraged me to go for it. I cleared the burn and ended up 12 feet from the hole.”

Benning was an independent sales rep in the golf business before joining Hanger, Inc., the leading U.S. provider of prosthetics and orthotics, where he is currently Marketing Manager. He has played other Open Championship courses but calls Carnoustie’s Championship layout “probably the greatest risk-reward course” in the rota. “Seeing it on television doesn’t do justice to the demanding test of golf it presents players,” he said.

To underscore his assertion, Benning cited the 6th hole – “Hogan’s Alley” – named after 1953 Open Champion Ben Hogan. Here is the description for it from the Carnoustie Golf Links website. “Normally played into prevailing wind, this can be a severe par 5. Bunkers and out of bounds await the miss-cued drive and although the best line is up Hogan’s Alley between the bunkers and the out of bounds fence, it requires a brave player to drive to that narrow piece of fairway. The second shot is no less perilous with a ditch angling across the fairway and the out of bounds continuing to be a threat. The approach is reasonably straightforward to an undulating green, particular care must be taken if the pin is located on the back-right portion of the green. A player should always be content with a five on this hole as it can be the ruin of many a scorecard.”

Benning said the pair of fairway bunkers side by side on the 14th hole – known as “The Spectacles – have to be experienced to be understood how hard they play for those unfortunate enough to find them.

“I hit into one of them during a match and it was the only time I had to hit backwards out of a bunker during the championship,” Benning remembered. “The face of the bunker was unthinkably high.”

The closing holes at Carnoustie’s Championship Course – Nos. 16-18 – may be the most difficult finish in all major golf, particularly No. 18, named “Home”.

“Just ask Jean Van de Velde,” said Benning, referring to the Frenchman who led by three strokes going to final hole of the 1999 Open Championship. Van de Velde took triple bogey to fall back into a tie and playoff, which he lost to Paul Lawrie. No golf follower who watched the debacle can forget the image of Van de Velde standing in Barry’s Burn with his trouser bottoms rolled up, hands on hips, stunned disbelief etched on his face. Conversely, Lawrie’s final round 67 astounded Benning, who pointed out that the final round average score was significantly higher. The 18th also cost Johnny Miller the 1975 Open title, after Miller took two shots to get out of a fairway bunker on the hole.

Suffice it to say, Carnoustie will provide many of the world’s greatest players the chance for immortal golf glory this week, or demoralizing defeat. Maybe both. Whomever emerges as champion, Mike Benning will relate to the elation felt after prevailing on one of the game’s greatest courses.
