Behind the numbers: A road map for an 18 handicap to get down to a 9

Published

on

I wrote an article four years ago for GolfWRX called “The statistical differences between a scratch golfer and a PGA Tour player.” This article became one of the most-viewed features for the site, totaling over 420,000 views to date. I recently consulted with Ben Alberstadt, GolfWRX’s Editor-in-Chief, about pulling together some numbers for handicap levels to which more of us can relate.

You might ask: How do I know the differences between these handicap levels? Well, it is my full-time job to know about the numbers behind the game of golf—at all levels. I have been a student of the game from a statistical standpoint for 30-plus years. I created the strokes gained analysis website, ShotByShot.com, used by thousands of amateur golfers to improve by isolating the strengths and weaknesses of their games. Additionally, I work with PGA Tour players to extract clear answers from the Tour’s overwhelming 650-plus ShotLink stats.

I’ve learned that there is no such thing as an “average” game, no matter the handicap level. We’re all snowflakes and find our own unique way to shoot our number. With that said, ShotByShot.com’s 384,000-plus round database enables us to create a composite of the average golfer at each level. One of the beauties is that our data is robust and smooth across all five major facets so that any golfer’s strengths and weaknesses—and we all have them—stand out clearly by comparison.

The Data We Used  

  • 18 Handicap: I averaged the 3,551 rounds in our database that match the 18 Differential from Slope Adjusted Course Rating. In other words, the Best eight of 20 rounds when Mr. 18   actually played to an 18 handicap.
  • 9 Handicap: Similarly, his Best eight out of 20 using the 5,000 applicable rounds in our database.

As you might guess, the difference between these two in scores is nine strokes. So, if your snowflake matches or is close to Mr. 18’s, simply drop the shots below by facet and voila you are there.

The chart below shows the distribution of the strokes by facet that Mr. 18 needs to save to join Mr. 9.

Driving

Skill in this critical facet of the game is measured by distance and accuracy. But let’s take distance out of the equation by assuming we’re all playing the correct tees for our games and focus on accuracy.

As the chart above indicates, we are looking for 2.5 strokes on, what for a typical golf course, is 14 driving holes. The chart below shows results in the average round for Mr. 18 and Mr. 9. Note that both make at least one Driving Error* per round. Weed out that error and you can be more than halfway home, especially if it is a Penalty Error** that tends to carry a cost of between 1.3 strokes (penalty with drop) and two-plus strokes (stroke and distance).

*No Shot Driving Errors = Balls hit out of play that cannot return to normal play with an advancement shot. 

**Penalty Error = a.  Stroke with drop, or b.  Stroke and distance. 

 

This may be easier said than done, but sometimes the fix is as simple as target and club selection from the tee. Sure, it works to aim away from trouble but try choosing a club that cannot reach the trouble. Most holes that feature trouble off the tee will also be stroke holes, even for Mr. 9. Avoid the error and take double-bogey out of play. This is also a valuable strategy for match play situations.

Next, strive to hit at least one more fairway. The approach accuracy charts below show how many more greens are hit from the fairway vs. rough.

Approach Shots

Here we need to save 3 strokes. This facet involves the greatest number of long game opportunities–on average 17.6 full swing attempts per round. These attempts are generally split 70 percent from the fairway and 30 percent from the rough. Let’s ignore the sand for now as it accounts for approximately only 1 shot every three-plus rounds. Except to say that when you find yourself in a fairway bunker, it is usually a mistake, so take your medicine, get back in play and avoid doubling the pain.

So where to save three strokes? Avoid penalties and that’s at least one stroke. Then hit three more greens in regulation and you’re there–Mr. 18 averages five GIRs vs. Mr. 9’s eight. The key is to improve accuracy.

I recommend working on the distance ranges circled in the charts below and devoting 70 percent of your work to fairway shots. From distances longer than the circled ranges, make smart choices, play within your capabilities and avoid errors and penalties. Easy?! At either handicap level, from long-range you’ll miss more greens than you hit. Knowing this, work toward “good misses” – the fat side of the green, short but in the fairway, etc. Finally, my data supports that hitting the green is far more important than worrying about “proximity to the hole”. But that’s another article.

Chip/Pitch Shots (within 50 yards of the hole)

Here we are looking to save 2 strokes in a less frequently used part of the game–ten shots per round for Mr. 18 vs. eight shots for Mr. 9. Again, please start with avoiding Errors*. My pro and mentor spent hours on the short game with me. First, valuable technique instruction and then competitions @ $1.00 per shot—best lessons ever! His method was to break the shot opportunities into three categories, and this goes for the Sand game as well. Try it—it works.

  • Green light: Good lie, no trouble–try to hole it
  • Yellow light: Difficult but doable–play conservatively and try to be left with an uphill, makeable putt.
  • Red light: Very difficult with looming downside–just get the ball on the green and avoid the error.

Next, practice the type of shots that you face the most and especially those that tend to give you problems. Bottom line, hit more shots closer to the hole and avoid costly errors. While this sounds like annoyingly obvious advice, maybe it will help to consider that Mr. 18 saves 20 percent of these opportunities vs. 32 percent for Mr. 9.

*Short Game Errors:  The shot misses the green AND requires 4 or more strokes to hole out.

 

Sand Shots (within 50 yards of the hole)

Here we are looking to save half a shot in a very small part of the game—just 2 and 1.6 shots per round respectively for Mr. 18 and Mr. 9. I view this an underrated skill that definitely produces more errors per attempt than any other part of the game. When I was learning the game, I was afraid of the gaping bunkers that surrounded and protected ALL of our 18 greens. It wasn’t until I worked hard to gain real confidence from the sand that the greens seemed larger and easier to hit. Again, avoid errors and you’ll solve this portion of the puzzle. Mr. 18 saves 12 percent of his sand opportunities (with 28 percent errors) vs. 21 percent saves for Mr. 9 (15 percent errors).

*Short Game Errors:  The shot misses the green AND requires 4 or more strokes to hole out.

Putting

Putting is 40 percent of the game at all levels and we need to save 1 stroke. EASY, Mr. 18 simply needs to reduce his 3-putts from 2.5 per round to 1.5. Do this by working on distance control from 20 to 50 feet.  Beyond 50 feet think of it as more of an easy chip shot with your putter. You’re doing well if you leave it within 10 percent of the original distance and below the hole. Finally, work on your short putts in the three-to-10-foot ranges. I recommend starting with three feet, then move to four to five feet. If you can get those ranges to Mr. 9’s one-putt numbers, you’re well on your way.

Conclusion

Bottom line, I have laid out where, on average, Mr. 18 needs to improve to make the leap to Mr. 9. If you made it this far, you may be saying, “Why all the focus on errors?” Simple! They are important! Most stat programs ignore them—the PGA Tour certainly does. My studies show that the relative frequency and severity of errors do more determine one’s scoring level than do all the good and average shots played.

Your game will no doubt have different areas of strength and weakness. The key is to accurately identify them so that you can address them appropriately. This article has hopefully given you some ideas about how to do that.

    I second the idea of doing another follow up article. Though, since your last article shows Mr. Scratch as a 73ish scoring average, maybe we could compare the single digit to someone that is averaging 1 or 2 under par. So I guess a +1 or +2 handicap would make a more informative comparison. We already have the stats for a 9 and 0 handicap based on this article and your previous, but it would be nice to have a reference for how to break par!

    Great analysis. I’ve learned (as a 20 handicapper) that I don’t need to hit the ball any longer (or even that much straighter) to be a 10 handicapper. All I need to do is take my best 9 holes and do it for 15 holes. No penalties. Quit using driver and switch to 3 wood at first sign of trouble (most holes only give you 0.2 strokes or so advantage with driver, one penalty outweighs the entire round). No muffed irons, no muffed chips, don’t hit into sand traps except with long irons. Aim for 2 putts instead of the cup. Wedge forward 70 yards from trouble vs. a low probability 150+ yard shot. If only my body wasn’t breaking down as I’m getting so much smarter.

    Is it possible to get the statistics to go from Mr. 9 to Mr. Scratch?
    pls don’t make me wait 4 yrs, I could be an 18 by then

      Chris,
      Certainly possible. I discussed with the Editor following up with 5 handicap to Scratch. IF, this article were well received.

      At the risk of sounding self-serving… If you subscribe to ShotByShot.com, you can select the lower handicap “Target” and the system will guide you to where you want to go. I suggest starting with the 6-9 Target range. When you get there, 4-5 and on down to 0-2 and even lower.
      Thanks for your question and please let me know how you do.

            The short answer is no. There is a golf course 1 hour away from me that is open, but I am only driving to work and the store. I rode my bike to my local muni but they are closed for now.

    I did just this. I did it by learning how to hit the ball straight, getting VERY good at approach putting and chipping, and learning how to play the game. There were other things, too, like learning how to hit from uneven lies, fairway bunkers, rough, greenside bunkers, chipping from strange places around the green, so I was seldom at a loss for how to stay on offense from challenging spots, but it was mainly those first three things.

    I’m with you 100% Jack! My long time friends and I, that used to relish the challenge from the back tees, now unabashedly pass them and walk proudly to the Sr./forward tees. The game is still as fun and competitive!

    Great article

    I haven’t used this tech language per say but over the years I’ve managed to play smarter. Getting older, having injuries and losing distance has taught me to use the right club(more club) more often and miss it on the proper side. Oh, and playing it forward makes the game fun again. If it’s feeling like work, you’re on the wrong tee box.

The Wedge Guy: A putting experiment

Published

on

One of the most fun and challenging things about this great game we all play is that there are myriad things to explore and try, keeping those that work for you and discarding those that don’t. While I realize many golfers just go out and play without giving it much thought, my bet is that most all of you who follow GolfWRX, and particularly weekly columns like mine, are always looking for ways to improve. I’m no different. In fact, I probably illustrate the extreme of experimentation because I’ve spent a lifetime in the game and over 40 years in the golf equipment industry.

In follow-up to last week’s post about the “Two putting triangles,” I thought I would share a recent experiment I’ve been conducting on my own putting. If this just gives any of you an idea that can shave a stroke or two, then I’ve earned my keep, so to speak.

I had been struggling on the greens a bit, not getting nearly as much out of my rounds as I thought I should. And one of the main culprits was that I was just not converting enough of my makeable putts. While my lag putting has been very good, leaving me very short second putts most of the time, where I thought I was sub-standard for an experienced low handicap player was in my success rate in making those “money putts” from 8-15 feet, and I felt like I missed more than my fair share of putts from three to eight feet in length.

To be honest, I tend to get a little “yippy” on those short putts sometimes, but it seemed that mostly my failure to make those putts drilled down to the face angle at impact. I might pull one and push the next one, so I decided to try something new a few rounds ago.

You all know I’m quite the follower and analyst of PGA Tour statistics as a benchmark for performance, so I started there to establish my goals. Here’s what I found.

The PGA Tour average from 4 to 8 feet is just under 69 percent. Given that these guys are the best in the world, have perfect greens every week and experienced caddies to give them a second set of eyes (which have also studied the greens extensively), I figured if I could attain a 50 percent sink rate from that range, I would be “golden”.
Moving out to the range of 10-15 feet, the PGA Tour average drops significantly, to just under 30 percent — only three out of every 10 tries from this range do the tour players make their putts. So, I figured given my recreational status, grainy greens and some very puzzling breaks on my golf course, my personal goal from 10 to 15 feet should be somewhere between one to two putts out of every 10.

In an effort to achieve this improved performance on those shorter putts, I began to experiment on my putting track at home with a “left hand low” grip on the putter. I’ve always gravitated to blade style putters, and usually have one of my own design in the bag. Many years ago, I became convinced that a face-balanced design improve my odds of keeping the face square through impact. But a couple of months before this experiment began, I received a putter from an industry friend that exhibited what is called “lie angle balanced,” the premise being that the face angle is essentially “built in” to the path of the putting stroke.
Anyway, I began to practice making putts of 7-9 feet on my putting track at home and explored its effect with a number of different putters that lean against the wall in my office — all while working to determine the right “left hand low” grip for me. What I found was that it was really easy to get in a groove on the putting track, so it was time to take this to the course.

I quickly found that my putting from these crucial distances visibly improved immediately with the left-hand-low grip. I reduced the action to a simple back and through, and both my “yippi-ness” and face control were dramatically impacted.

So, then I began to keep some stats of my own and here’s what happened over the course of the next 10-12 rounds.

My make percentage on putts under eight feet has improved to almost 60 percent, not that far below the PGA Tour average. Wow. And on putts of 8 to 15 feet, my make percentage leaped to 22 percent, even closer to the tour average. As you can imagine, my golf buddies noticed the change and my scoring dropped by as much as 3-4 shots per round.

Where I’m keeping it different is that I putt the longer putts with my comfortable conventional grip, as it engages the fingertips of my master right hand for optimized touch and feel. So, when success is more about speed than line, I go conventional. But inside 15 feet or so, I employ the left-hand-low grip as those putts are more about line than speed.

While I have always been quite the traditionalist in my approach to this game, I like making putts and shooting lower scores as much as any of you. If you are not converting shorter putts as often as you think you should, you might give this two-grip approach a try.
