Handicap Information The formula used by GolfLog to produce the Handicap Index has been revised to provide results that should match the Handicap Index provided by both the United States Golf Association and the Royal Canadian Golf Association. 컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� Differentials: The Handicap Index is determined based on the differentials from a selected number of 18-hole rounds a Golfer has played. The criteria for selecting these differentials is as follows: Number of Differentials Rounds Used ~~~~~~~~~ ~~~~~~~~~~~~~ 5 ---- Lowest 1 of all 18-hole rounds 6-7 ---- Lowest 2 of all 18-hole rounds 8-9 ---- Lowest 3 of all 18-hole rounds 10-11 ---- Lowest 4 of all 18-hole rounds 12-13 ---- Lowest 5 of all 18-hole rounds 14-15 ---- Lowest 6 of all 18-hole rounds 16-17 ---- Lowest 7 of all 18-hole rounds 18 ---- Lowest 8 of all 18-hole rounds 19 ---- Lowest 9 of all 18-hole rounds 20+ ---- Lowest 10 of last 20 18-hole rounds Note that after a Golfer has 20 or more rounds of 18 holes the lowest 10 differentials from the immediate past 20 rounds are used. Only differentials from full 18-hole rounds are used. All differentials from 9-hole rounds, if any, are discarded Differentials are determined by the following method: When the Gross Score is higher than the course Rating, the course Rating is subtracted from the Gross Score. When the Gross Score is lower than the course Rating, the Gross Score is subtracted from the course Rating. The next step is to multiply 113 by the figure from the above calculation then dividing that figure by the course Slope. This figure is carried to ONLY ONE decimal place WITHOUT ROUNDING. Example: A Golfer shoots a Score of 86 on a course with a Rating of 71.5 The Rating of 71.5 is subtracted from the Score of 86 giving a result of 14.5 113 is multilpied by 14.5 giving a result of 1638.5 This is divided by 133 producing a result of 12.3 which is the Handicap Differential for this game. 113 x 14.5 = 1638.5 = 12.3 (Differential) 컴컴컴 133 GolfLog automatically determines the Handicap Differential for each game at the time it is recorded and saved in the database. 컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� Course Handicap: A Golfer does not play off his/her Handicap Index. Rather a Course Handicap should be determined using the following method: Multiply the Handicap Index by the Slope value of the course being played and divide by 113. The resulting figure is ROUNDED to the nearest whole number (.5 is rounded upward). Example: A Golfer with a Handicap Index of 11.7 playing on a course with a Slope value of 133 11.7 x 133 = 1556.1 = 13.7 (round to 14 for Course Handicap) 컴컴컴 113 To obtain the Slope value of a Course, contact the Club Professional or Manager. In many cases, both the Slope and Rating are listed on the club's score card. When adding a Game Record to the database, GolfLog will automatically determine the Course Handicap for that round. 컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� Be this as it may, the Handicap Index provided by GolfLog is not to be considered as ones "official" Handicap Index. It cannot be used in place of the Handicap Index provided by the U.S.G.A. when entering tournaments The Course Handicap provided by GolfLog should closely match that provided by the U.S.G.A. and the Royal Canadian Golf Association (provided the same Slope and Handicap Index values are used). To get a quick Course Handicap use the "Quick Handicap" option in GolfLog. 컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� OverAll Differential: The figure shown as a Golfer's OverAll Differential is based on the Golfer's Handicap Index. This figure can be used to measure improvement over days, weeks, months, etc. 컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� NOTE: It is imperative that Game Records be entered in the order they were played (by date). < End Of File > ~~~
