Part1:Introduction to PGA and LPGA averages
http://www.mytrackman.com/TrackMan.Online.DrivingRange/PGANumbers.html
Below is a list of PGA and LPGA Tour Averages. The data is based on thousands of shots from ranges all over the world. Numbers provided by TrackMan Range are available from Driver to PW. Find your weaknesses and enforce your strengths - compare yourself to the pros!
Behind the PGA numbers
Notice how the PGA Tour players manage to combine a high launch angle (10-15 degrees) with a low spin rate (2-3000 rpm) to gain maximum distance with their driver. The landing angle is on average kept below 40 degrees for the driver and near 50 degrees with irons. Further note the fixed gaps from 3-iron to PW - there is around 10 meters between each iron on average.
Since the ball speed of an average male club golfer is similar to the ball speed of LPGA Tour players, a comparison to LPGA Tour numbers, rather than PGA Tour numbers, is often beneficial for the average male golfer.
LPGA Tour averages
Behind the LPGA numbers
Notice the lower ball speed for LPGA Tour players compared to PGA Tour players. This is why women carry the ball shorter than their male counterpart. However, LPGA Tour players utilize their ball speed better than PGA Tour players because they launch the ball higher with the same spin rate. This is a more efficient use of power.
Further note that women generally spin the ball less, resulting in lower height (apex point), and have a shallower landing angle - more roll.
Golf Scoring Statistics of Average Golfers
http://probablegolfinstruction.com/golf-scoring-statistics.htm
Although much is known about the statistical profile of professional golfers, little has been published on the play of other golfers. Riccio's 1990 paper used data from over 100 golfers ranging in ability from Jack Nicklaus to a 35 handicapper. The analysis was designed to determine which aspects of play separates the average players from the top amateurs.
I've also done an analysis of PGA Tour Tournament results from 2007. Scroll down to view.
He found that some specific statistics were good predictors of score. For example, the number of pars made could be used to accurately predict score, using the equation,
SCORE = 102.6 - 2.7 X #pars. If a player typically makes 7 pars each round, his/her likely average score would be 102.6 - 2.7 X 7 = 83.7.
Take a look at how many pars you usually make in a round (analyze your last 5 rounds). What does the above formula predict for your average score? Is it a good predictor?
Another good predictor is greens in regulation, GIR. The formula Riccio discovered for GIR is SCORE = 95.1 - 2.0 X GIR. If you are an excellent ball striker and happen to hit on average 15 greens per round, then your likely average score would be 95.1 - 2.0 X 15 = 65.1. Yes, 65! The pros don't hit on average 15 greens per round.
Below is a table which summarizes some of the statistics that Riccio investigated. Where do you fit in with your game?
The last column indicates the strength of the statistical relationship between score and the statistic. A "Strong" relationship is one that predicts quite well one statistic given the other (i.e. the SCORE given the GIR). A "Weak" relationship does not predict as well.
Part2:Golf Swing Tempo and Rhythm
Tempo refers to the speed of the swing, and rhythm refers to how well all the parts of the swing work together.

Novosel closely analyzed video of most of the world's greatest golfers, both past and present, and discovered that virtually all of them executed their swings, from take-away to impact, within a very small window of time, from .93 seconds to 1.2 seconds. He also discovered that nearly all accomplished golfers have a precise, identical rhythm: three beats back, one beat down. Novosel then devised a way for average golfers to approximate the tempo of a pro swing by hitting balls while listening to tones through a headset and watched in amazement as their shots improved instantly and dramatically—without any attention whatsoever to wrist cock, hip turn, swing path or the countless other mechanical issues that are the bane and substance of traditional instruction. This improvement happened essentially, Novosel came to realize, because once the tempo is right, there isn't any time left over for the club to do all the crazy, inefficient things it usually does during bad swings, like pause, hitch, wander around in loops and come over the top.
Broadcast video is shot at a rate of thirty frames per second. For one of LPGA top players, no matter what club was using: twenty-seven frames from take-away to the top, nine frames from the top back down to impact, for a total of thirty-six frames, or 1.2 seconds.
The fastest swingers, like Nick Price, Ben Hogan and Jack Nicklaus, took twenty-one frames to reach the top of their backswings and seven frames back to impact, for twenty-eight frames total and .93 seconds total swing time. Another group, including Tiger Woods, Ernie Els and Sam Snead, took twenty-four frames back and eight frames down, for 1.02 seconds total swing time. And a third group, including Bobby Jones, David Toms and Jim Furyk, swung consistently at a 27:9 tempo. Of the more than one hundred pros whose swings Novosel studied, only one—Ed Furgol, the 1954 U.S. Open champion—swung faster than 21:7 (he swung at 18:6), and only a handful swung slower, including Nancy Lopez in her prime (30:10). But always, the three-to-one time ratio of backswing to downswing was identical.
The only time the swings of the best players in the world diverged from this ratio was when they hit bad shots. When you try to hit the ball too hard, your tempo quickens. Don't try to hit a driver any harder than any other club. Use the same tempo.

When talking about their golf swings, people often use the words “tempo” and “rhythm” interchangeably. However, the two are not the same. Tempo refers to the speed of the swing, and rhythm refers to how well all the parts of the swing work together. For this reason, some teachers use words such as “flow” to encompass both aspects. You need both tempo and rhythm to have a consistent and powerful swing.
Physical Strength Limits Tempo
Your physical strength places a practical limit on the tempo of your swing. The faster you swing, the more forces your swing generates. If you are not strong enough to control these forces, you will lose control of the club and mishit shots. You should be able to swing properly at a slower tempo, where the forces are not greater than your ability to control them. This helps you determine the proper speed for your swing.
Relaxation Helps Rhythm
Teacher Bob Toski writes that you want to “surrender to the swing.” Relaxation--letting the club do the work while you gently guide it--is something most teachers try to teach. Think of the times you have been told to grip the club lightly; to take an athletic posture with your knees slightly bent, rather than standing stiffly at address; or to “waggle” the club before swinging. Such “active relaxation” helps you stop working against the movements in the swing; rather, you allow them to happen.
Movement Smooths Rhythm and Tempo
Good rhythm generally maximizes your swing’s tempo, and good tempo smooths out your swing’s rhythm. David Leadbetter advises his students to avoid standing still over the ball; he prefers that they begin a gentle motion before swinging. One of his drills involves holding the club a foot ahead of the ball, then swinging it back without hitting the ball to start the backswing and ensure that the movements in the swing blend together more smoothly.
The Rhythm of Tempo
In one of the more scientific attempts to quantify tempo, author John Novosel studied film footage of many great golfers, measured the time (in film frames) they took to make a good swing, and published his findings in a book called “Tour Tempo.” Novosel found that, while some players had slower tempo swings than others, almost all had a backswing three times longer than their downswing. This finding helped show how rhythm and tempo were related.
Practicing the Two Together
Perhaps the simplest guideline for improving both tempo and rhythm was given by Bob Toski and Davis Love Jr.: “We aren’t proponents of swinging slowly. On the contrary we want you to swing the clubhead as fast as you can without losing control.” If you can both retain your balance during your swing and hit the ball accurately, you are not swinging too fast and all the parts of your swing are working together properly.
