APL GOLF LEAGUE HANDICAP SYSTEM

Overview

A player must have a Current League Handicap Index to participate in 9-hole Flight Play.  For League Tournament Play, if a player does not have a Current League Handicap Index, the player will be considered a “scratch” (zero handicap) golfer until a League Handicap Index is established.

 

The USGA Handicap System uses differentials between adjusted gross scores and the "USGA COURSE RATINGS" (not course par) as well as the “USGA COURSE SLOPE” in handicap index calculations. The APL Handicap System uses the same values and formulas as the USGA System, except in two circumstances.  APL uses a different number of scores in the calculations and APL uses ONLY rounds of golf played in the APL League.  This will include league match rounds, tournament rounds, and rounds play as a substitute.  A description of the USGA Handicap System can be found online at: http://www.usga.org/Handicapping.aspx?id=7792

Differentials are obtained by subtracting the adjusted gross scores from the course rating, then multiplying by (113 / course slope).  This makes the differential independent of the difficulty of the course played.  The formula is shown in TABLE I.

Handicap indexes are calculated by averaging a number of differentials (based on how many scores are available, up to 10), and rounding off to the nearest tenth.  This formula is also shown in TABLE I.

Course Handicap and Adjusted Course Handicap

When playing a match in the league, you must compute your Adjusted Course Handicap for the particular course you are going to play.  To calculate the Course Handicap, you must multiply your Handicap Index by the Course Slope and divide by 113, rounded to the nearest integer.  To compute your Adjusted Course Handicap, you add the difference in course ratings (rounded to the nearest integer) between the tees you will be playing and the rating of the middle tees.  This computation and examples are shown in TABLE II.  The USGA has a very good publication describing this calculation and why it exists at:  http://www.usga.org/playing/handicaps/understanding_handicap/section_3-5_Brochure.pdf

For league golfers who have scores on record (last two years), handicap determination will be in accordance with this formula using the differentials already recorded. All differentials are restricted on a per hole basis according to the U.S.G.A. Equitable Stroke Control (ESC) System given in TABLE III. When fewer than 10 differentials are available, determine the number of differentials to be used from Table I.

Tee Box Rating and Slope

In the APL Golf League, men play from the ‘middle’ tees, women play from the ‘forward’ tees, seniors (men 60 and over) play from the ‘senior’ tees, and super seniors (men 80 and over) play from the ‘forward’ tees.  These three tee boxes are determined individually for each course played (i.e. many courses have more than three tee boxes), but are generally the front three tee-boxes available.

Tee box ratings and slopes are generally available for men from the Middle and Senior tees and for women from the Forward tees.  Tee-box ratings are generally not available for men from the Forward tees (which is required for the super seniors).  Therefore a rating and slope must be calculated for the super seniors using a table provided by the USGA (http://www.usga.org/Rule-Books/Handicap-System-Manual/Rule-05/ Section 5-2g).  This table computes ratings and slopes for ‘temporary tees’ based on the difference in yardage between the nearest rated tees and the tees being played.  These computed rating and slope values are used for super seniors.

Definitions of and Establishing a League Handicap

Definitions:

Current League Handicap Index – The League Handicap Index on record for the current year or from the previous two years.

Current USGA Handicap Index - A USGA Handicap Index is issued through licensed golf clubs that follow all the procedures of the established USGA Handicap System™,* (for example www.msga.org, www.pagolf.org, www.vsga.org, etc…) AND must be publically verifiable.

Establishing a League Handicap Index:

Note: If you have a Current League Handicap Index, this section is not applicable.

      9-hole Flight Play – To establish a League Handicap Index for 9-hole Flight Play, a player is required to have a current USGA Handicap Index (as defined above) OR may submit the scores and course information (slope, rating, and tees played from) for two nine-hole qualifying rounds (where the lower of these two scores will be used to establish the golfer's handicap index for the first league match).

      Substitutes (Flight Play) - To establish a League Handicap Index for play as a Substitute, a player is required to have a current USGA Handicap Index (as defined above) OR must participate in an APL Individual Stroke Play tournament**.

      League Tournament Play – To establish a League Handicap Index for League Tournament Play, a player is required to have a current USGA Handicap Index (as defined above) OR must participate in an APL Individual Stroke Play tournament**.

In the event of a dispute or a special consideration involving the establishment of a player’s league handicap, the Executive Committee shall be responsible for making the final determination.

** The resulting scores from the APL Individual Stroke Play tournament will be used to establish the player’s League Handicap Index in the same manner as 9-hole Flight Play (as defined above) with the tournament scores used in lieu of “qualifying rounds”.

 

Handicap Updates

Since many golfers are now playing in multiple flights, it was determined that golfers should have a single handicap across all flights played in.  (At one time, golfers maintained a different handicap for each flight and they were sometimes quite disparate from flight to flight).  In order to maintain a single handicap for each golfer, all scores for each flight are used in this computation. 

In order to maintain some type of synchronization, it was then decided to update handicaps on a periodic basis (as opposed to updating them after every match played).  It should be fairly clear why this is necessary.  Say a golfer is playing in two flights and plays one match on Monday for flight A and on Tuesday plays another match in flight B.  How does this golfer know what handicap to use on Tuesday?

Short of requiring all golfers maintain their own handicaps, it was decided to update league handicaps periodically.  Specifically, handicaps are updated every Sunday at midnight.  Therefore, when a golfer plays in more than one match in a particular week (independent of when the match was scheduled), they will use the same handicap index for each of these matches.  Of course, for each match you must compute your Adjusted Course Handicap (based on course slope and the difference between the rating for the middle tees and the tees being played).

A note for players with newly established league indexes; for the first handicap index update, the lower of the low qualifying round and the score of the first league match will be used for determining the handicap index. After the second league match has been played, the low qualifying round is dropped from any further consideration and from then on TABLE I is used as the basis for handicap updates.


This Handicap System is designed to accomplish the following things:

A.  Provide fair handicaps for as many golfers as possible, even though their abilities vary widely.

B.  Reflect the player's inherent ability as well as his recent scoring trends.

C.  Automatically adjust the playing handicap down or up as his game changes.

D.  Disregard freak high scores or holes that bear little relation to the player's normal ability.

E.  Make it difficult for the player to obtain an unfairly large handicap increase at any revision period.

F.  Establish handicaps useful for all golf from formal league play to informal games.

Differential = (Adj Gross Score – Crs Rating) * (113 / Crs Slope)

Handicap index = 0.96 * differential average (truncated to nearest tenth)

Example 1:

Last 10 Differentials = 4.5, 5.6, 3.4, 8.7, 6.8, 10.2, 4.3, 8.8, 6.2, 4.8

Lowest 5 Differentials = 4.5, 5.6, 3.4, 4.3, 4.8

Handicap Index = 0.96 * (22.6 / 5) = 4.3392 => 4.3

 

Example 2:

Only 4 Differentials = 13.4, 16.7, 21.2, 13.9

Lowest 2 Differentials = 13.4, 13.9

Handicap Index = 0.96 * (27.3 / 2) = 13.104 = 13.1

MAXIMUM HANDICAP INDEX = 30.0

 


TABLE II

ADJUSTED COURSE HANDICAP COMPUTATIONS

Course Handicap = Handicap Index * ( Crs Slope / 113 ) (Rounded to nearest integer)

Adjusted Course Handicap = Course Handicap + (Tee Rating – Middle Rating)

Example 1: Female golfer with an index of 4.2 playing on a course with a rating of 35.6 from the middle tees and a rating and slope of 36.7 and 123 from the forward tees.

Handicap index = 4.2.
Tees / Slope = Forward / 123
Ratings = Forward: 36.7, Middle 35.6
Course Handicap = ( 4.2 * 123 / 113 ) = 4.57 => 5
Adjusted Course Handicap = 5 + (36.7 – 35.6) => 6

Example 2: Senior golfer with an index of 13.1 playing on a course with a rating of 35.6 from the middle tees and a rating and slope of 34.7 and 134 from the senior tees.

Handicap index = 13.1.
Tees / Slope = Senior / 134
Ratings = Forward: 34.7, Middle 35.6
Course Handicap = ( 13.1 * 134 / 113 ) = 15.53 => 16
Adjusted Course Handicap = 16 + (34.7 – 35.6) => 15
