There is also a hole limit of « net double bogey » for handicapping purposes in order to prevent one or two bad holes from having a disproportionate effect. A new WHS handicap requires several scores to be submitted; the recommendation is a minimum of 54 holes made up of any number of 9 or 18-hole rounds in order to achieve a reasonable fair and accurate result, although handicaps may be issued from a smaller sample. The WHS is based on the USGA Course and Slope Rating system, and largely follows the USGA Handicap System while also incorporating features from the six major existing handicap systems. Nationally, the peer review is extended further to assessing golfers from external jurisdictions for their suitability for entry into their elite international events. This gives uniformity to handicapping across their club for the setting and maintenance of handicaps with the objective of establishing fair competition between golfers of all abilities.
Stroke allowances may sometimes be reduced by a set percentage in order to maintain the level playing field; this is especially common in pairs and team competitions. In handicap Stableford competitions, a player’s handicap is distributed according to predetermined hole ratings (stroke index) and strokes deducted accordingly from each hole score before calculating the points for that hole. The adjusted gross score in ‘world handicap system’ is the gross score adjusted such that the maximum on any particular hole is the number of strokes taken for a hole + the handicap allowance for that hole + 2 strokes , i.e. net double bogey,. While the USGA administers its own handicapping system, the administration of handicapping systems in countries affiliated to The R&A is the responsibility of the national golf associations of those countries. While these systems share some common features — e.g. most use a common course rating system, they are not easily portable because their differences create difficulties in converting handicaps between systems. One of the first standard and equitable handicap systems was introduced by the Ladies Golf Union (LGU) in the 1890s.
It is based on Stableford scoring and has some similarities to both the CONGU system, with regards to handicap categories and adjustments, and to the USGA system, with regards to the use of course and slope ratings and calculating playing handicaps. The handicap differentials are rounded to one decimal place, and the best 10 from the last 20 submitted scores are then averaged, before being multiplied by 0.96 (the « bonus of excellence ») and truncated to one decimal place to produce the handicap index. The handicap index is not used directly for playing purposes, but used to calculate a course handicap according to the slope rating of the set of tees being used with an adjustment based on the difference between the course rating and par. The score differentials are rounded to one decimal place, and the best 8 from the last 20 submitted scores are then averaged and rounded to one decimal place to produce the handicap index. For other handicapping systems, the differentials are simply the difference between the , adjusted, gross or net scores and a specified standard rating (e.g. course rating, standard scratch score, etc.), and they are used in different ways to maintain handicaps.
Systems for handicapping
The handicap is not used directly for playing purposes and a calculation must be done to determine a « playing handicap » specific to the course being played and set of tees being used. EGA handicaps are given to one decimal place and divided into categories, with the lowest handicaps being in Category 1 and the highest in Category 6 , see table below,. Under the EGA Handicap System, initial handicaps require just a single 9 or 18-hole score recorded using the maximum handicap of 54. The EGA Handicap System is the European Golf Association’s method of evaluating golf abilities so that players of different standards can compete in handicap events on equal terms. In addition, any very good scores are monitored throughout the year and an exceptional scoring reduction may be applied if certain triggers are reached. Handicaps are given to one decimal place and divided into categories with the lowest handicaps being in Category 1.
Once a month, handicaps are refreshed, derived from a lookup table that calculates the average of the best eight differentials from the previous 16 rounds. Typically, a starting handicap of 25 is employed, which then undergoes modifications based on the scores betting and predictions submitted. Although this required several further adjustments (such as changes in playing handicap and differential calculations), all other functions of the system (including Adjusted Gross and the absence of daily course rating modifications) remained intact. Before 2012 (handicaps were calculated based on an adjusted Standard Rating), referred to as Calculated Rating, but this practice was halted.
Slope Rating
A couple of adjustments are then made to this total to give the player’s handicap, which is then applied to their gross score as normal. When players have completed their rounds, they apply the Peoria algorithm to their scores on the selected holes to determine their handicap for that round. Before play commences, the organisers secretly select 6 holes , in readiness for handicapping purposes later, from the course to be played. The Peoria System was designed for the handicapping of all players competing in an event such as a charity or corporate golf day.
- New handicaps require 3 18-hole scores to be submitted (or any combination of 9 and 18-hole scores totaling 54 holes played) using a « Temporary Daily Handicap » of 36 for men or 45 for women in order to calculate the necessary « sloped played to » results.
- Each individual union administers the system on behalf of their members (while CONGU publishes it; locally), at each club, handicap management is typically overseen by a competitions or handicap secretary.
- In addition to playing in qualifying competitions, golfers in Category 2 and above may also submit a number of extra day scores in order to maintain their handicap.
- The EGA Handicap System stipulates that a single score from either a 9 or 18-hole round is sufficient for establishing initial handicaps, utilizing a maximum handicap of 54.
Maximum hole score
The number of strokes taken on each hole is adjusted to maximum of double the par of the hole before adding up the scores; adjustments were previously 2 over par for men and 3 over par for women. The organization was tasked with creating a handicapping system that would be equitable to golfers of varying ability — and as a result the Standard Scratch Score and Handicapping Scheme was devised. The handicap index is not used directly for playing purposes, but used to calculate a course handicap according to the slope rating of the set of tees being used. If there are at least 5 but fewer than 20 qualifying scores available, the handicap index is calculated using a set number or differentials according to how many scores are available. Initial handicaps are calculated from a minimum of five scores using ESC adjustments based on the course handicap corresponding to a handicap index of 36.4 for men or 40.4 for women. A USGA handicap is calculated with a specific arithmetic formula that approximates how many strokes above or below par a player might be able to play, based on the ten best scores of their last twenty rounds.
This is done by means of « soft » and « hard » caps based on the lowest index during the previous 365 days; the soft cap reduces increases above 3.0 to 50% — and the hard cap limits increases to 5.0. For competitions (the unrounded course handicap is converted to a playing handicap by applying a handicap allowance), dependent on the format of play. 9 hole scores may be submitted for WHS calculation, with an expected score for the player’s handicap index is used to produce an equivalent 18-hole score differential. Ongoing handicaps are based on the average of the best 8 differentials, but with an « anchor » to prevent rapid increases that would not necessarily reflect the player’s true potential. For players with current handicaps (their handicap records in the old systems will be used to produce WHS handicaps; the expectation is that most players will at most see a difference of one or two strokes), if any. For example, 8 differentials , like the Golf Australia system, are used after net double bogey adjustments (like the CONGU and EGA systems) for handicap calculations, and the WHS course/playing handicap includes a course rating adjustment (like the EGA system).
During the late 19th century, taking the difference between the average of a golfer’s best three scores during the year and par became the most widely used method of handicapping in England and Scotland. According to The Golfer’s Manual by Henry Brougham Farnie, examples of agreed terms included « third-one » , one stroke every three holes,, « half-one » (one stroke every two holes), « one more » (a stroke a hole) and « two more » (two strokes a hole). The number of strokes to be given and the holes on which they would be in effect was negotiated between competing golfers prior to the start of play.
Features of handicapping systems
With the system still not accounting for variances in playing difficulty for golfers of different abilities — in 1979 the USGA set to work on how to address the issue with the creation of the Handicap Research Team. In 1974, Equitable Stroke Control was adopted in order to eliminate the effect of very high individual hole scores on handicap calculations. Course ratings were rounded to the nearest whole number until 1967, when they started being given to one decimal place. The first handicap system to be introduced by the USGA was largely the work of Leighton Calkins, who based it on the British « three-score average » system where the handicap was calculated as the average of the best three scores to par in the last year.
In most major handicapping systems, a golfer does not use their exact handicap , or handicap index, directly, but use it to produce their playing or course handicap. Some handicapping systems provide for an adjustment to the course rating to account for variations in playing conditions on any given day (e.g. course setup and weather), and it is against this adjusted rating that handicaps are assessed and maintained. In handicap stroke play competitions (a golfer’s playing handicap is subtracted from the total number of strokes taken to produce a net score), which is then used to determine the final results.
The two most prevalent methods for establishing a maximum score on a hole are Equitable Stroke Control (ESC) and net double bogey, also known as Stableford Points Adjustments. A maximum score is set for each hole, which is exclusively for handicap calculations; it does not influence the outcomes of competitions or matches. Many widely used handicap systems aim to mitigate the effect of extremely high scores on specific holes when computing and updating handicaps. Each golf course hole is assigned a Stroke index number, usually found on the scorecard, which indicates where handicap strokes should be applied. During match play, the difference in handicaps between players , or teams, determines how many strokes the higher handicap player receives from the lower handicapper throughout their round, with these strokes allocated on the lowest numbered stroke index holes. The gross score for a hole , or round, refers to the total number of strokes taken before factoring in a golfer’s handicap, while the net score indicates the number of strokes after any handicap allowance has been deducted.
The differentials are used both to calculate initial handicaps and maintain existing ones, by taking a mean average of a set number of the best recent differentials (e.g. the USGA system uses the best 10 differentials from the last 20 scores). They are a standardized measure of a golfers performance, adjusted to take account of the course being played. The lowest numbers are usually given to the holes where a higher handicapper is most likely to benefit — and the highest numbers to the holes they are least likely to benefit. A playing handicap may also refer to the stroke allowance for a given competition dependent on playing format, and is generally calculated as a percentage of the course handicap.
