Using statistics and launch monitor data to shoot lower scores



As a statistician who works with PGA Tour players, I’m frequently asked by aspiring Tour players and their coaches what statistics they can use to measure themselves against Tour players.

The mistake with this question is that the playing grounds for aspiring Tour players and actual PGA Tour players are often different. In fact, metrics on the PGA Tour can change drastically from one event to another. For instance, the average make percentage of putts from 3-to-5 feet for the year is roughly 87 percent. At the AT&T Pebble Beach National Pro-Am, however, the average make percentage for professionals from 3-to-5 feet was only 76 percent. Thus, a golfer that made 80 percent of their putts from 3-to-5 feet would be putting poorly on many Tour courses, but doing better than average at Pebble Beach. And the same applies for shot proximity to the cup. Some courses are easier than others and for aspiring Tour players. It is not easy to gauge their performance versus the PGA Tour players performance since it depends on the degree of difficulty of the course.

Don’t get me wrong. I do think that using PGA Tour benchmarks can be useful, but expecting that they will provide golfers with an accurate depiction of how the average Tour player would perform on a course is misleading at best. Instead, I advise golfers to focus on what I call their “game profile.” A game profile is various strengths and weaknesses of a golfer’s game. It’s how well they putt, drive the ball, what happens when they drive it effectively or ineffectively, how well they hit their short approach shots, mid-length approach shots and long approach shots and how well they perform with their short game around the green.

The game profile starts with power and how far a golfer hits the ball off the tee. How far a golfer hits the ball dictates what the rest of their game will generally have to look like in order to achieve success. But first, what we should understand is that the biggest advantage to hitting the ball far is that it affects how well golfers will have to putt the ball. And the farther a golfer hits the ball, the more likely he or she can get away with poor putting. Here is a chart showing many of the super-long hitters on Tour and their 2013 PGA Tour performance in money, driving distance and the strokes gained – putting categories.

Table 1

Conversely, here’s a look at the shorter hitters on Tour that were successful and their rankings.

Table 2

The biggest reason why the long hitters can get away with weaker putting is that they often have the distance to play the par-5’s in two shots like they are par-4’s. And they are getting more birdie opportunities on those holes, because they’re often hitting it closer to the cup.

The problem with using distance for the aspiring Tour player is that virtually every golfer who tells me how far they hit the ball will give me a number of when they hit the ball the best without the weather conditions affecting their distance. Even Tour players do not consistently make great contact with the ball and are far from being overly consistent with how far they hit their driver.

And that is where launch monitors can help. In 2013, the average club head speed on Tour was 113.6 mph. The highest club head speed was 124.5 mph by Charlie Beljan, and the lowest was 104.7 mph by Jin Park. These numbers should give an initial indication of how much power a golfer has compared to the Tour.

Another important factor to consider is the attack angle. I am not trying to advocate any particular attack angle for a golfer. We know that all things being equal, the more golfers hit up on the ball with a well-fit driver the farther the ball will travel. Therefore, if a golfer has a very downward attack angle, but generates 113.6 mph of club head speed, he or she is effectively now as powerful off the tee as a golfer that may have less club head speed, but hits well up on the driver.

Lastly, we need to consider the Apex Height. The average apex height of a Tour player in 2013 was 96.9 feet. The highest was 131.7 feet by Jason Day. And the lowest apex height was 67.5 feet from Scott Langley. There is a statistical correlation between a player’s apex height and success on Tour. While it is not a strong mathematical correlation, it is substantial enough that it warrants attention. Obviously, golfers with higher club head speeds generally will hit the ball higher, but there are many low club head speed players that hit the ball high and have had resounding success like Brandt Snedeker, Ben Crane, Mark Wilson and Luke Donald, to name a few. What my research has uncovered is that there are too many courses on Tour that favor golfers with higher ball trajectories. I attribute this to the modern course designs, which have more forced carries than older courses.

Once a golfer gets their club head speed and attack angle readings, they can start to determine how much power they have off the tee compared to the rest of the Tour. And for any player, I generally recommend a goal of keeping their fairway bunkers hit to under 5 percent (roughly one fairway bunker hit every other round). As far as hitting the fairways goes, it is rather simple. The farther golfers hit the ball, the lower percentage of fairways they have to hit. Here is a chart of the recommended goal of fairway percentage hit based on club head speed in order to be effective off the tee:

Table 3

When we examine the table showing the successful lower club head speed players and putting combined with the recommended fairway percentages by club head speed table, we start to see that it becomes virtually impossible to make the PGA Tour if you cannot generate at least 104 mph of club head speed. Once a golfer gets below 104 mph, it requires them to hit such a high percentage of fairways and to putt so incredibly well that they are going to have a hard time keeping their card because golfers can only be so accurate and putt so well.

This leads into power and its influence on the game profile and the player’s ability to hit approach shots. I break down approach shots into three different zones:

  • Birdie Zone (shots from 75-to-125 yards)
  • Safe Zone (shots from 125-to-175 yards)
  • Danger Zone (shots from 175-to-225 yards)

In general, the Danger Zone is the most important zone in golf. In fact, it has the strongest mathematical correlation to success on Tour. Regardless of club head speed, the player’s performance on Tour is largely dictated by how well they play from the Danger Zone. And there is not a substantial correlation between club head speed and Danger Zone play.

My research leads me to believe that this is because the Danger Zone shots requires golfers to have directional and distance control, whereas shots from the Birdie and Safe Zones are more distance-control oriented. The angle for error from the Danger Zone diminishes because it is such a long shot. So while generating more club head speed will have golfers hitting shorter clubs from the Danger Zone, the angle of error diminishes so much that golfers with slower club head speeds like Jim Furyk, Zach Johnson, Luke Donald and Graeme McDowell can get the advantage because of their superior directional control from this zone.

What often happens with the long hitters is that they may not actually be that skillful with their irons, but still rank well from the Danger Zone. This is because most of their Danger Zone shots are coming on the Par-3’s. When the rest of the field is playing a long par-4 and can only manage to leave themselves with 175-to-225 yard shots into the green, the long bombers can hit their drives to 125-to-175 yards. This is one of Bubba Watson’s strengths, because historically he has not been a good iron player. If there was a contest from 200 yards between Bubba and Jim Furyk, I would take Furyk. The difference is that in competition Bubba is hitting his approach shots from a much shorter distance than Furyk the majority of the time and that levels the playing field, or even gives the advantage to the lesser skilled iron player.

As I discussed earlier, the shorter hitters normally have to putt better because they cannot hit their second shots as close to the hole on the par-5’s as the long hitters. This also means that slower club head speed players need to hit it better from 100-to-150 yards in order to catchup to the rest of the field on those par-5’s. Shots from 100-125 yards are generally where the shorter hitter will end up laying up to. Even if their “money yardage” is less than 100 yards, the majority of the time they can only lay up to 100-to-125 yards. And if they hit a weaker tee shot, then their lay-up shot tends to move more towards 125-to-150 yards.

Here is a table showing some notable players’ 2013 ranking on shots from 100-to-125 yards and their club head speed with the driver.

Table 4

If the higher club head speed players were better from 100-to-125 yards, it would have a positive impact on their performance. However, due to their high club head speed, performing well from 100-to-125 yards is a lower priority than it is for the lower club head speed players.

The game profiles are something that the average amateur can use as well. For example, golfers who play to a 10 handicap but hit the ball short for that handicap level and do not foresee themselves increasing their club head speed substantially in the future may want to follow the example set. There is a warning; the distance of the “Zones” changes for amateurs because they are playing shorter courses. So if golfers are playing courses that are roughly 6,000-to-6,300 yards, their ‘Danger Zone’ will about 150-to-200 yards and the Birdie Zone will be about 50-t0-100 yards. But the same game profile concept will remain the same.

The shorter-than-your-average-10 handicap player may want to work more on his putting, focus more on hitting more fairways and on his wedge play. The longer-than-your-average-10 handicapper may want to focus on keeping his drives in play more often so they can use that length to his advantage. This can help players from all levels take the path needed to shoot better scores.

    I have recently calculated on a full round of 18 holes the gained/lost strokes compared to a PGA pro and based on the “gained stokes concept” implemented by Mr Broadie.

    Let me share with you my results that will interest quite a few of you down here 😉

    The great advantage of the method is that it quantifies the number of strokes you loose on each part of your game. I found this new concept a revolution ! I for example can now focus on my long game (>165 yards)of my game where I “lost” 6 strokes last week…

    See below the complete calculations and explanations I made:

    Great read, thanks for posting it. One question: are those tour statistics readily available for the average person to see?

    Great article, but how do I know if I am a “shorter than average 10-hcp”? Do you have a table with average distance per handicap?

    • RollTheRock

      Mar 13, 2014 at 10:50 am

      As a follow up, if you are a shorter than average 10, and you improve upon the other aspects of your game, your handicap will drop, making you a significantly shorter than average 6 or wherever you get to. It almost seems like there is an implied floor to how low your handicap can within reason based on distance off the tee. If you hit the ball 250, which is average for let’s say a 10hcp, and get down to a 5, to improve further assuming you can’t get any more distance off the tee, you would have to become incredibly accurate or an amazing putter. It would be awesome if there was some way to quantify this. A chart or data that says to be a scratch golfer with an average distance of 250yds off the tee, you would typically have to hit x% of fwys, gain y strokes from the danger zone, and gain z strokes putting. And then perhaps be able to play with x, y and z. For instance, I can hit x% of fairways but I don’t gain enough strokes in the danger zone, however I can gain z+ strokes putting.

      Sorry for the nerd rant, but that would be cool.

        That was one of the parts I struggled with. There were some researchers from Australia that did research and found that handicap and club head speed do have a very strong correlation to each other. They did a regression analysis to come up with a handicap to ball speed analysis, but I could not get the formula to compute correctly. Something I am working on.

        This is a related article on what to work on based on statistical analysis.

        Basically, you take your fractional remaining length (distance remaining to target / total distance from original spot). If your FRL is ~5-6% you should be hitting it 297 yards, ~8-9% 248 yards, ~12% 237 yards, 17.3% 216 yards. If you hit it farther, work on your short game, if you hit it shorter work on your long game.

    This is definitely better than your article last August about whether Trackman is ruining golf.

    I have 2 beefs with this.

    First, the title. “Statistics & Launch Monitor Data”. The only launch monitor data you use in this article is club head speed. All of the rest of the data is from Shotlink. You mention that it’s important to hit up on a driver and it helps to hit a high ball, but you give no analysis or data on these issues. When I clicked on this story, I was expecting something about Trackman and all of the awesome data it provides. I felt teased.

    Second, what is your main point? Shorter hitters need to be straighter drivers, better wedge players and better putters to compete with longer hitters? Duh! Do you need to crunch a bunch of data to convince people of that?

    The structure of this article is also a bit of a mess.
    Here’s an outline of your article:

    – Tour averages vary from course to course. (So what? This has nothing to do with the rest of your article.)
    – Pros need to look at their individual strengths and weaknesses.
    – The longer you hit the ball, the worse you can be at putting and still compete.
    – Shorter hitters that succeed on tour are good putters.
    – Launch monitors help you maximize distance for a given swing speed.
    – Longer hitters don’t have to hit as many fairways to be competitive.
    – Longer hitters have shorter and easier approach shots.

    Your argument boils down to this: longer hitters have an advantage. No one will argue with that. Tell us something interesting.

      I used more than just club head speed. I discussed attack angle and also used Apex Height of the ball. I also never discussed ‘launch monitors help you maximize distance for a given club head speed.’ The article does not recommend any particular attack angle, but it discusses power, how to more accurately measure it and understand how this will impact the rest of yoru game.

      Lastly, long hitters do not always have easier approach shots. If they are in the fairway bunker or deep rough or the trees, that’s not the case. That’s why long hitters rarely win at Sawgrass (Tiger won last year, but was hitting 3-wood on virtually every hole). As I stated in the article, they are likely to have more easier shots into par-5’s. However, they still have to keep the ball on the grid. A player like Luke List didn’t stand a chance last year despite being the longest player on Tour because he couldn’t keep the ball in play.

      +1 on this. I was expecting some analysis on swing speed vs. ball speed or something…

      • Richie Hunt

        Mar 13, 2014 at 1:45 pm

        I tend to avoid using ball speed because there are many factors to ball speed and often times the ball speed measurement is not quite accurate. I also think that the average golfer relates more to club head speed than they do ball speed.

    These types of articles with statistics are more informative for me. It breaks down the stereotype of trying to hit it farther. For a recreational golfer like myself, we constantly read articles and see commercials on how to hit it far just to have bragging rights. This article just proves how hitting it far is not always a good thing to do.

    • Richie Hunt

      Mar 12, 2014 at 5:15 pm

      Thanks for the kind words. I think my main point is that there are more than one way to shoot better scores and to understand what power does for a golfer’s game. If you are legitimately able to add 25 yards to your game and still be fairly consistent doing so, I would certainly take it. But if you can’t legitimately add substantial power and you hit it short, you need to look at putting better and hitting your wedges better while finding more fairways.

    Fascinating! As a shorter-than-average 8 handicapper, I’ll always lack the go-low potential of longer hitters but as long as my up & downs are roughly equal to the GIRs I’m giving away straight drives and short game focus let me compete with friends 20 years younger and 30 yards longer. And when I can depend on my short game, there is less pressure to attempt a high trajectory, 180 yard approach shot; in effect, I can shrink the danger zone on a hole-by-hole basis by playing to my strengths rather than gambling on my weakness.

    this is an exceptionally well written article. one of the best i have seen on dictating the correlation between the PGA tour courses, the skill set they demand and the strengths and weaknesses of each individual player on tour. excellent read for coaches and players alike!

    There is obviously a Long game/ Short game teeter-totter effect. Do you think this has something to do with the nature of golf and it’s equipment? I often think that these long hitters would benefit from a balanced approach to their swings and equipment. More 43″/ 100 g shafted drivers in the hands of the high swing speed players would increase their consistency (not as big of difference in feel from driver to irons).

    The driver swing is different than the iron/ wedge swing… is it a coincidence that no one does both really well?

Golf 101: How do I putt?



May seem like the most mindless aspect of the game, but it’s actually the polar opposite. How many times have you seen a new golfer seemingly wonder, “how do I putt?” then stand up to a putt and either pull it back like a 1/2 inch and gun through it or take it back knee-high and hit the brakes at impact?

The point is, new golfers rarely understand the idea of controlling the pace and violence of the impact.

Without getting into arcs, release, etc., let’s just focus on a simple way to stay in your body and hit a 4-footer. How do we do that? Eliminate as many variables for chaos as humanly possible.

How do I putt?

Four checkpoints to, at the very least, keep the ball on the green and somewhere near the hole.

  1. The Grip: Club falls in the lifelines of your palms. I don’t care if it’s ten-finger, traditional, interlock, cross-handed, or anything else. The point is putting the grip down the lifelines eliminates any tricks your fingers can play and just by association secures your lead wrist in a flat position.
  2. Stance: Feet shoulder-width apart, arms hang under your shoulders and eyes are over the inside part of the ball. The ball should be just shy of the middle of your stance, so split the difference between your lead heel and your pants zipper. Simple enough. Watch Tiger, just like that.
  3. Pick your spot: Find a spot 6-12 inches in front of you and focus on rolling the ball over that spot. A) It will get the ball on your intended line B) It will help you begin to understand the harmony of line and speed C) It gets you focused on your intention as opposed to your stroke.
  4. Toe to Toe Shoulder Rocking: Once you are set up, the ball is properly placed, you got your aim point and now….. rock the shoulders. That’s it. You will see the upside-down triangle you have created with the correct setup, on a pendulum rock that triangle, and by default, the back of the lead hand will lead the train and collect the ball hopefully outta the middle of the face. This is the most important thing (for now), the clubhead never gets past your trail toe and passes all the way to your lead foot for the follow thru. Once you get a sense of speed control you can venture outside of the toe to toe reservation.

Yes, this will take some getting used to and mistakes will happen, but once you get your mental image to match up with your body action its a surefire way to instill sound fundamentals into your stroke all while eliminating all the “extra stuff” we do when learning how to putt. You can put your signature on it once you get the hang of it. One miracle at a time.
