Five things you need to know about the new World Handicap System

I love the USGA. Over the next 16 years, I helped establish the use of Slope Rating throughout the United States and many other countries. I offer this preamble to underscore that I have no grudge against the association. I strongly support its work in handicapping. What was a straightforward and careful system has become something more complicated and less precise. And American golfers will immediately feel its changes. At the risk of getting wonky, here was the old formula:. Under the new WHS, however, course handicaps reflect the strokes you get in relation to par with a subtle but significant change to the formula.

This par-based adjustment Course Rating minus Par has been part of handicap systems in a handful of countries but for specific reasons. It originated in Sweden and Australia, where golf is often played using a Stableford format based around scores in relation to par on each holeand points, not strokes, are posted for handicap purposes. It made sense then that their formulas would include a step to add par to the equation. What does not make sense, though, is applying the par adjustment throughout the rest of the world, in particular to the U.

Almost any golfer can list two courses that are both par 72s but vary greatly in how tough they play. Differences in length, in obstacles, in penalty areas, make one drastically harder than another even when they have the same par. Par as a metric, then, is somewhat arbitrary.

Where this issue becomes noticeable is how the new formula changes course handicap values from tee to tee as you compare the WHS to the USGA system at any course. For example, where once a course handicap was a 12 from the back and middle tees, and an 11 from the front, under the new WHS calculations there will be much larger variations—as many as 18 shots in some instances—between tees.

Let me try to apply this to real-world scenarios. Under the WHS, due to the par adjustment, his range now varies from -1 to 22 with an average course handicap of An aside: Scratch golfers are no longer 0 handicaps everywhere.

They could be playing anywhere from a plus 12 to a 6 handicap. Players who play from the same tees at their club will see another inconsistency. Say your Course Rating is The calculation of Course Rating minus Par comes out to. Based on the way course handicaps are calculated, half the players will have their playing handicap drop one shot lower in the WHS but the other half will not; it all depends on how that.

As we all know, one stroke often determines handicap-event outcomes.Any combination of 9 or 18 holes. How do I move clubs on the new system? Notify your new club that you have kept a Handicap in the past.

They will initiate a transfer process through Golf Canada. This will retain all your scoring history and Handicap Index. How long do my 20 scores last on the new system? Scores will not expire.

However, to maintain the most accurate handicap it is recommended that players continue to post all eligible scores.

Can my handicap lapse?

No, if you retain membership your Handicap Index will remain valid. If your membership does lapse, your account will no longer compute a Handicap Index. Scores are not deleted at this time. If your membership is reactivated, the Index will be computed again based off scores existing in the account.

What will happen to my existing playing history when WHS comes into effect? The scores you currently have in your record will be used to calculate your new Handicap Index. What is a slope rating?

When will I as a golfer know what my Handicap Index will be? The aim is to show all members a sample of their new Handicap Index towards the end of the season. How do the daily course conditions affect the score? The WHS includes a Playing Conditions Calculation PCCwhich will analyze how players have performed that day compared to their expected performance on that golf course.

It will naturally include weather and course setup reflected in the scoresand if expected results fall outside a tolerance level, an adjustment will apply to all scores played on that course for that day. A Playing Conditions Calculation PCC can only be calculated if at least 8 scores from players with fully developed Handicap Indexes have been entered on that day.

What happens to the Playing Conditions Calculation PCC if the weather is significantly different in the morning to the afternoon? Scores should be entered as soon as possible.

World Handicap System: Key questions answered

What would happen if a score is not returned quickly, is there a time limit? Scores should be entered before the end of the day approx. Any scores not entered before that time will still be acceptable but will not be used as part of the PCC determination. However, the PCC determination for the day of play will still be applied when the score is posted.

Yes, there is still a seasonal need for an Active Handicap Season. With other tools available within the system, each Provincial Association has the right to choose their seasonal dates to which scores played in that region are acceptable for Handicap purposes.

What restrictions will a Committee be able to place on handicaps for club competitions? As with any competition, the Committee can have a set of Conditions which may include a handicap limit. Will your handicap change over hole events? What is the recommended minimum number of scores per year that should be submitted to maintain an accurate Handicap Index? Will we still need a Club Handicap Committee?


Yes: a club will still need to appoint a Handicap Committee to manage and maintain members handicaps e. What is a playing handicap and what does it consist of?Please note that this page explains the calculations that existed through December 31, Curious how your golf handicap is calculated?

The USGA golf handicap formula is not rocket science, so anyone - even non-math folks - can understand how to determine their golf handicap. What math functions will you need to know? How about addition, subtraction, multiplication, division, rounding and truncating? Simple enough? This article will dissolve any difficulty related to figuring an hole USGA handicap. You use the Handicap Index to calculate your Course Handicap for any particular course.

Again, remember that your Handicap Index is the same from course to course. Your Course handicap, a number for a specific course, is determined using your Handicap Index.

ESC is used to downwardly adjust individual hole scores for handicapping purposes in order to create handicaps that better represent a golfer's playing ability.

world handicap system formula

ESC imposes a maximum number of strokes that can be entered for any given hole. This maximum is based on the golfer's Course Handicap and is obtained from the table shown below. An example of a downward adjustment may be helpful.

Let's say that a player with a Course Handicap of 18 scores a nine on one of the holes. His nine would be downwardly adjusted to a seven because players with handicaps in the 10 to 19 range are allowed a maximum score of seven on any given hole. Once you make adjustments, if necessary, to all eighteen holes, the sum of these 18 holes is the Adjusted Gross Score.

The second step in computing a Handicap Index is to compute a Handicap Differential for each score that is to be considered in the Handicap Index calculation.

The Handicap Differential is computed using the following formula:. Round the Handicap Differential to the nearest tenth i.The formula to calculate a Handicap Index remains average-based. But there are distinctions with the WHS that golfers should understand when the system goes live in the United States and dozens of other countries in January.

Here are five to remember. Fewer scores count toward your Index. With the WHS, that number falls to eight of your past The reduction, Edmondson says, allows for greater responsiveness to good scores and rewards more consistent play.

Your Index updates in your sleep. Those accustomed to getting a new Index the first and 15th of each month, take note. That rhythm changes under the WHS, with a new Index calculated daily or at least any day after a golfer posts a new score. This is meant to create a more responsive handicap and keeps players from having to wait up to two weeks for new scores to have an impact. Tournament committees beware: It will be best to establish clear cutoff dates for handicaps.

Welcome to the net-double-bogey world. ESC was calculated on a sliding scale, depending on your course handicap could take no more than a 7 on any hole, took a max of 8, etc. The WHS also has a maximum, but it uses net double bogey as the universal standard. This provides consistency in its application and is a nod to handicap systems used in other parts of the world, particularly those that use Stableford scoring, where net double bogey is the equivalent of zero points.

Your Index will weather the storm. Modern technology can tell you within a yard of how far you are from the flag on any hole. Say 20 mile-per-hour winds cause you to shoot in the high 80s when you normally post 78s and 79s. The WHS algorithm accounts for this to keep the score from negatively affecting your Index, particularly if all scores that day were high.

Previously, your course handicap represented the number of strokes you got based on your Handicap Index in relation to course ratinga metric that only the most avid golfers knew or understood.

Now course handicaps reflect the strokes you get in relation to para more intuitive measure for most golfers, Edmondson says. Tournament chairs will appreciate this. Note that course-handicap values from tee to tee will vary more under the new system.

Golfers playing forward tees will get fewer strokes than before, and those playing back tees will get more. Here's How To Do It. With the World Handicap System launching in January, there are more reasons than ever to do it.

How Is Golf Handicap Index Calculated? Here's the Formula

You just need to complete 54 holes to qualify. Not good enough? The maximum Handicap Index has been raised to 54, so it works for golfers of all skills. USGA studies show golfers with handicaps make better connections inside the golf community and play more rounds.

If you carry an official USGA Handicap Indexthe calculation is performed for you by other people or, far more likely, by a computer.

You can also get an unofficial estimate of your handicap by using a golf handicap calculator. But you want the nuts and bolts of the handicap formula, don't you? You want to know the math behind figuring handicaps. OK, you asked for it, you got it.

What numbers do you have to have in order to perform the handicap index calculation? The formula requires the following:. Using your adjusted gross scores, the course ratings, and slope ratings, Step 1 is calculating the handicap differential for each round entered using this formula:.

For example, let's say your score is 85, the course rating The formula would be:. The sum of that calculation is called your "handicap differential. Note: The number is a constant and represents the slope rating of a golf course of average difficulty.

Not every differential that results from Step 1 will be used in the next step. If only five rounds are entered, only the lowest of your five differentials will be used in the following step. If 20 rounds are entered, only the 10 lowest differentials are used. Use this chart to determine how many differentials to use in your handicap calculation.

Get an average of the differentials used by adding them together and dividing by the number used i. And the final step is to take the number that results from Step 3 and multiply the result by 0. Drop all the digits after the tenths do not round off and the result is handicap index.

The flaw in the new World Handicap System

Let's give an example using five differentials. Our differentials worked out to just making up some numbers for this example So we add those up, which produces the number Since we used five differentials, we divide that number by five, which produces And we multiply that number by 0. Thankfully, as we said at the beginning, you don't have to do the math on your own. Your golf club's handicap committee will handle it for you, or the GHIN system if you log in to post scores.

Just imagine: Once upon a time, these calculations were all done by hand. Reason to be thankful for computers, right? Brent Kelley.Currently, in order to obtain a Handicap Index, you must submit five hole scores. This can be a mix of 9-hole and hole rounds and will be revised on the 1st and 15th of every month. With the new changes coming ina Handicap Index can be obtained after submitting only three hole scores. Again these can be a mix of 9-hole and hole rounds.

Also with the new system in place revisions to your Handicap will now be daily, just as long as you post your third hole score by midnight. The reason for this change is to accommodate players who play off different tees. These golfers are playing with different benchmarks so this new calculation will help to make it a fairer game.
