What is USGA Golf Course Rating and Who Rates It?

How does slope affect your golf shots?

And as it falls it continues to move forward. Depending on the slope of the land, this could affect the distance of your shot anywhere from 20 to 50 yards. That’s no small change! A smart course architect actually uses this effect to trick the golfer.

What are slope and par on a golf course?

There's par for a golf course, and then there are two other numbers on the scorecard: golf course rating and golf course slope (or, simply, rating and slope). You may have never looked too hard at slope and rating and you might be wondering what they are, what they tell you and how they're determined.

What is the average slope of an 18 hole golf course?

The United States Golf Association established the average slope rating to 113, but it has later increased to about 120 as there aren’t many 18-hole golf courses with slope ratings set that low. As has been observed, most golf courses worldwide have average slope ratings of about 120.

How do you determine the slope of a golf course?

Slope ratings are in the range from 55 to 155, with a course of standard playing difficulty having a rating of 113. In order to calculate the slope rating, the difference between the bogey and scratch rating is multiplied by 5.381 for men and 4.240 for women.

How do you determine course rating and slope?

Course Ratings represent the difficulty of a golf course for the scratch player under normal conditions. Slope Ratings represent the difference in difficulty for all other players, compared to the scratch player. Course Ratings are carried out by qualified teams, and assume normal course and weather conditions.

How is handicap slope calculated?

Handicap differential = (Adjusted Gross Score-rating of the course) X 113 / Course slope ratings. The course rating is simply the scores of a new golfer on a normal course under a normal playing condition. Slope rating is the rating of 113 for a course based on the standard difficulty.

How does golf slope rating work?

What is a Slope Rating® and what does it represent? A. Playing length and obstacles impact higher-handicap players more than lower-handicap players, and Slope Rating measures the relative difficulty of a golf course for players who are not scratch players compared to those who are scratch players.

Is a 130 slope rating hard?

If you see a slope rating that falls anywhere in the double digits, you can expect that course to play rather easy, even for a bogey golfer. On the other hand, taking on a course with a slope rating in the 130's or 140's is going to present a serious challenge to a player with a mid or high handicap.

How is course rating calculated?

The Course Rating is calculated from the effective playing length and obstacle factors for 9 or 18 designated holes. The Course Rating is expressed in strokes to one decimal point and represents the expected score for a scratch player. The Bogey Rating represents the expected score for a bogey player.

How do I calculate my 2021 course handicap?

Use the following formula to compute the Handicap Differential: Handicap differential = (The Adjusted Gross Score -The Course Rating) X 113 / The Course slope ratings. The course rating refers to the score of a new golf player on a course under standard playing conditions.

How do I calculate my 2020 course handicap?

Course Handicap Calculation Pre-2020 the calculation to find the Course Handicap was: Handicap Index X Slope Rating/ 113.

How does slope affect your handicap?

Slope merely tells you how “proportionately” more difficult that particular set of tees plays for the higher handicapped golfers as opposed to lower handicapped golfers. The more difficult the tees play proportionately for the higher handicappers, the greater the Slope rating that will be issued. That's it!

Why is it important to know the slope of a golf ball?

This is because, while you may calculate the distance between you and the flag in a straight line, you do not hit the ball in a straight line. The ball is hit at an arc and with a trajectory that effects how far it actually goes.

What does it mean when you walk uphill or downhill?

Anytime you walk uphill or downhill you are walking up or down a slope. Think of triangle on its side and you’ll see a slope. On the course, we deal with this all the time because a shot that goes from one point to another that is at the same height is the exception rather than the rule.

Can a rangefinder be used in a golf tournament?

According to Appendix IV of Rule 14-3 no measuring device that calculates for slope may be used during tournament play. This does not mean, however, that your rangefinder cannot be used at all. The USGA does allow for a Local Rule to permit a “stipulated round” in which measuring devices like rangefinders can be used.

Does not taking slope into account hurt your score?

But we can certainly say that failing to account for slope will certainly hurt your score. This is because you will likely be under or overhitting the ball. As you get better with adjusting and factoring in slope, you should see some improvement in your overall score.

Can GPS calculate slope?

While GPS might be able to give some indication of your relative elevation, it won’t be able to calculate slope for your specific situation. This doesn’t make it useless, but means that a course with a lot of height changes will reduce its effectiveness quite a bit.

Can a GPS track slope?

So, a GPS device will not be able to calculate for slope, but only estimate your distance to different predetermined locations on the course.

Is it harder to play golf without knowing the slope?

What is clear is that playing without knowing the slope is a whole lot harder. This also depends on how much the course you play changes in elevation. A relatively flat course will not factor in much slope at all. On very hilly courses, failing to factor for slope could cost you dozens of strokes.

What is the average slope rating for golf courses?

The United States Golf Association established the average slope rating to 113, but it has later increased to about 120 as there aren’t many 18-hole golf courses with slope ratings set that low. As has been observed, most golf courses worldwide have average slope ratings of about 120.

What does slope number mean in golf?

Thus, the slope number converts a golfer’s handicap into a course handicap. In this way, it is made sure that a bogey golfer is allowed to play at an equal level to a scratch golfer, and it helps them obtain enough strokes from the same set of tees. This is the mathematical formula of how it is derived:

When did the slope rating start?

USGA introduced the slope rating measurement in the 1980s as a system of fairness directed to bogey players. Namely, they observed that a bogey golfer is likely to increase the number of strokes considerably more when playing on a course with a higher level of difficulty than a scratch golfer. This led to creating a slope handicap system ...

Do golf courses affect the slope number?

Yes, they do. However, the course rating impacts the golfer’s index considerably more than the slope number. It often happens that players become too focused on the slope number while ignoring the golf course number.

Myth No. 1 – Slope is the primary indicator of difficulty or, to put it another way, the higher the Slope, the more difficult the course

Wrong! As the above example confirms, it is the Course Rating and not the Slope, which is the more dominant factor in defining course difficulty.

Myth No. 2 – Slope ratings can he compared between courses

Wrong! I wish I had a dollar for every letter, E-mail or phone call I have received criticizing existing ratings on the basis of the Slope only. In short there is nothing more dangerous than trying to draw any sort of meaningful conclusions by comparing Slope Ratings from one course to another.

So what is Slope?

Slope merely tells you how “proportionately” more difficult that particular set of tees plays for the higher handicapped golfers as opposed to lower handicapped golfers. The more difficult the tees play proportionately for the higher handicappers, the greater the Slope rating that will be issued.

What is the slope rating of a bogey golfer on a course?

However, if bogey-golfers on course A averages a score of 90 while bogey-golfers on course B average a score of 95 the slope rating for course B would be higher than for course A; indicating a higher level of difficulty for higher handicap players.

What is a course rating?

The simple answer is, a course rating is a number that indicates what a scratch golfer (a golfer that averages par for a round) should shoot on this particular course. So, while the par for a particular course might be 72, a course rating of 70.1 would indicate that a scratch golfer should be almost two under par on average.

What is slope rating?

The Slope Rating reflects the relative difficulty of a course for players who are not scratch golfers in comparison to scratch golfers. Golfers use the Slope Rating, a trademark of the United States Golf Association, to calculate handicap differentials. The rating falls between 55 and 155; the higher the number, the more challenging the course.

How does weather affect golf scores?

Since golf is a game that is played outdoors, weather or other conditions can significantly affect a player's scores. As such, in an effort to more accurately represent a player's scores, an adjustment, referred to as the Playing Conditions Calculation (PCC), based on playing conditions for the course is included. This involves factoring in a number, ranging from -1 (when conditions make the course easier) to 3 (when conditions make the course more difficult), into the score differential calculation, depending on the conditions of the course for the given day.

What is a golf handicap?

A golf handicap is intended as a measure of a golfer's potential playing ability. The higher the handicap of a golfer, the poorer the golfer's ability relative to that of a person with a lower handicap.

Why is it important that players submit their scores on the actual day of play?

Because this adjustment is dependent on a given day, and since it is calculated automatically , it is important that players submit their scores on the actual day of play so that the PCC will be applied to their score on the correct day.

What is the trajectory of a golf ball?

The trajectory of a golf ball is now well understood. It depends on ball velocity, trajectory, and spin as well as on air temperature, humidity and density. Below is a graphic of the trajectory of a golf ball hit with a driver, 5-iron, and 9-iron. Note that in the first part of each trajectory, the path of the ball steepens.

Which is steeper, 9 iron or driver?

The 9-iron 's impact is the steepest and the Driver's impact is the least steep. Because of this, a Driver's range is more greatly affected by elevation changes than a 5-iron and the 5-iron's is more greatly affected than the 9-iron's. For every yard of fall, the Driver ball travels farther.

How far does a 6 iron go downhill?

Thus, the effective distance of the 6-iron is 21 yards shorter. If hitting downhill to a green, 20 yards below, the ball lands ont he green at a horizontal distance of about 180 yards. Thus, the effective distance of the ...

Why is the downhill drive longer?

Even if there was no roll, due to very damp fairways, the downhill drive would be longer. ". It's not always obvious to golfers that when hitting uphill, you need to hit more club and when hitting downhill, you need to hit less club. The question is how much more or less. Of course, it depends on many conditions.
