Equitable Stroke Control
Equitable Stroke Control (ESC) is the downward adjustment of individual hole scores for handicap purposes in order to make handicaps more representative of a player’s potential scoring ability. ESC sets a maximum number that a player can post on any hole depending on the player’s Course Handicap. ESC is used only when a player’s actual score or most likely score exceeds his maximum number based on the table below. There is no limit to the number of holes on which a player may adjust his score.
If you are out of the hole and pick up to speed up play, write down the score you would most likely make. For handicap purposes you are required to adjust your hole scores (actual or probable when they are higher than the maximum number you can post.)
EQUITABLE STROKE CONTROL

9 OR LESS DOUBLE BOGEY
10 THROUGH 19 7
20 THROUGH 29 8
30 THROUGH 39 9
40 AND OVER 10
The Handicap Index
Each player’s handicap index is published every two weeks by the GHIN system. It is updated as new scores are turned in. The index is a calculation based on the lowest 10 scores out of the last 20 posted. It can be calculated from a minimum of 5 scores. Each player should receive notification of their of their handicap index by e-
Handicap Index X Slope Rating = Course Handicap: 113
Note that the three South Shore Harbour courses have slope ratings of 120, 121, and 122 from the red tees. Players may have a different handicap on each 18 holes once the index is plugged into the above calculation. (The course rating is not used to determine a course handicap.) This is rounded to the nearest whole number.
Calculating a net score for LGA play days
The handicap is applied to the course by distributing the extra strokes to be substrated from par to the hardest holes first. An example looks at a player with a 23 handicap who is playing Shore/Harbour. The first 18 strokes are distributed one each to all 18 holes; the other 5 strokes are given on the hardest holes for each 9 (front and back.) Thus on Shore, the scorecard lists #9, #1, and #7 as the first, second and third hardest holes. On each of these holes the 23 handicap player will get 2 strokes. On Harbour the scorecard lists holes #1 and #6 as the hardest, so the player will get 2 strokes on each of these holes. When a handicap is an even number, the extra stroke is always applied to the front nine holes. Net scores for each hole are the gross unadjusted score for each hole minus the strokes applied to each hole. Alternatively a player may subtract the whole handicap from her gross score. (See equitable stroke control chart.)
Post only an Adjusted Score
Additionally, when recording gross scores in the GHIN system, the gross score must be adjusted using the equitable score control table. This removes the effect of abnormally high individual hole scores (like a 12) by establishing a maximum score per hole depending on the player’s handicap. This is below and printed on our course scorecards. (Example: a 20 handicap player shoots 105 with a 9 on one hole; accordingly to equitable stroke control a 20 handicap will adjust the 9 to an 8 and the player adjusted handicap will adjust the 9 to an 8 and the players adjusted gross score is 104. A 104 is posted in the GHIN system.
On play days, you will record Gross, Adjusted and Net scores, and the pro shop posts the adjusted scores in the GHIN system. Rules of golf dictate that all rounds played should be posted in the GHIN System. This assures a fair calculation of handicap index and thus ensures players of different proficiency to play against each other on somewhat equal terms.
Course Rating and Slope
In the United States each officially rated golf course is described by two numbers, the course rating and the slope rating. 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 (who shoots par on every hole) on that course. The slope rating of a particular course number is a number between 55 and 155 that describes the relative difficulty of a course for a bogey golfer (who shoot over par on every hole) compared to a scratch golfer. These two numbers are used to calculate a player’s handicap differential, and from that a handicap index is calculated.
WITHOUT HANDICAPS BETTER PLAYERS WOULD ALWAYS WIN AND DESTROY THE EQUALITY AVAILABLE FOR PLAYERS OF ALL ABILITIES TO FAIRLY COMPETE.
