Golf Course parameters
Each officially rated golf course is described by two numbers: the course rating (CR) and the slope rating (SR). The course rating of a particular course is a number generally between 67 and 77 that is used to measure the average "good score" by a scratch golfer on that course. The slope rating of a particular course is a number between 55 and 155 that describes the relative difficulty of a course for a bogey golfer compared to a scratch golfer. These two numbers are used to calculate a player’s handicap differential, which is used to adjust a player’s score about par according to the slope and rating of the course. The slope rating for a golf course of average difficulty is 113
The CR and SR is provided by the field or national federations and is different for each outing of a course for both 9 and 18 holes. Usually they are usually printed on the score cards and on the websites of practically all courses.
Golf player parameters:
The player’s real handicap (HR) that is calculated by averaging the individual handicap (HI) obtained in the eight best results of the last 20 scored in this way, takes into account the trajectory and not only the result of an isolated match. Indicate that you have to score at least three 18-hole games to start having a real handicap assigned.
The Course Handicap (CH) is the one assigned to the player for the course where he will play and is calculated with this formula:
The Individual Handicap (HI) or handicap index is the one obtained in a round and is calculated with the following formula:
Regarding the extra points.
The Result Adjusted to Handicap (RAH) is calculated with the following formula:
The Adjusted Gross Result (RBA) is obtained adding the blows made in each hole but in those holes in which the double bogey has exceeded the par of game assigned to the player for that hole, a double bogey is scored. This prevents them from penalizing the holes where we have very poor results, that is, the equivalent of having 0 Stable Ford points (this is what we know as a line which allows us to raise the ball if this value is exceeded in order to speed up the matches.
The Par for each hole is calculated by distributing the points of CH between the most difficult holes in the field, that is, starting with the holes with the least handicap, to increase the pair of each of them.
As an example n player with HJ 3 would have three points to share, imagine that the three most difficult holes are a pair 3, 4 and 5, in this case would become par 4, 5 and 6 respectively. A player with HJ 18 would have 18 to deliver one more stroke on each hole. One with 20 would have 2 holes with 2 more strokes and 16 with one more and so on.
The main purpose of a handicap system is to allow players of different levels of play, both men and women, to compete in balanced conditions.
In stroke play, it is used to calculate a net score from the number of strokes played during a competition, thus allowing players of different proficiency to play against each other on somewhat equal terms. In match play, the handicap difference between players is used to determine the number of strokes the high handicap player should receive from the low handicapper during the playing of their round.
The higher the handicap of a player, the poorer the player is relative to those with lower handicaps. Official handicaps are administered by golf clubs with regional and national golf associations providing additional peer reviewing for low and very low handicaps respectively.
The World Handicap System is expected to launch in January 2020. It is designed to welcome more players, to make golf easier to understand and to give all golfers a handicap which is portable all around the globe.
It will replace the six different systems currently used by over 15 million golfers in more than 80 countries.
On January 1, 2020 comes into force the World Handicap System (WHS), a new way to measure the handicap in a unified way for all countries in the world that replaces all previous ones (USGA, EGA, CONGU, ...).
The new WHS system has these characteristics:
It is global, it can be applied in different fields and countries, this requires that all courses have data from the USGA Course and Slope Rating System that is already used successfully in more than 80 countries and allows introducing weather difficulties if they are relevant.
It is flexible allowing computing both the scores of the tournaments and those obtained in games of entertainment, in this way the handicap of a player adjusts more effectively to his real ability even if he does not play tournaments regularly.
Allows daily revisions and updates of the handicap.
To make the game more enjoyable, the new system will include:
Course rating and slope rating
Minimum number of scores to obtain a handicap
Competitive and recreational scores to count for handicap
Handicaps will be calculated from an average of recent scores
Maximum handicap of 54
Abnormal course and weather conditions adjustments
