Calculating Senior Men’s Interclub
Course Handicaps

A player will not qualify for a Senior Men’s Interclub index until he has completed 3 rounds under this system.  Once he is qualified for a Senior Men’s Interclub index the following applies:

 

HANDICAP DIFFERENTIAL

For each Senior Men’s Interclub round played a “Handicap Differential” is calculated as follows:

Handicap Differential = (Adjusted Gross Score – Course Rating) x 113 /  Slope Rating   (The result is then rounded to the nearest tenth)

ROUNDS USED IN CALCULATIONS

  • After 3 rounds the lowest Handicap Differential is used to calculate a player’s Handicap Index

  • After 4 rounds the two lowest Handicap Differentials are used to calculate a player’s Handicap Index

  • After 5 rounds the two lowest Handicap Differentials are used to calculate a player’s Handicap Index

  • After 6 rounds the three lowest Handicap Differentials are used to calculate a player’s Handicap Index

  • After 7 and subsequent rounds the oldest round is dropped from the calculations and only a player’s most recent six rounds are used as described above.

HANDICAP INDEX

The first step required to calculate a Senior Men’s Interclub handicap index is to determine the number of handicap differentials to be used (1 min,  3 max).  See above.

The differentials determined in step one are averaged and multiplied by .96.  All decimal numbers after the tenths digit are then dropped.  This gives a player’s Senior Men’s Interclub handicap index.  So……

Index = (no. of Differentials total / no. of rounds) x .96 (All decimal numbers after the tenths digit are then dropped).

COURSE HANDICAP

A player’s course handicap is determined by multiplying his Senior Men’s Interclub handicap index by the slope rating of the course to be played and then dividing by 113.  That number is then rounded off to the nearest whole number.  (.5 rounds up to the next whole number).  So…..

Course Hdcp = Index x Course Slope / 113 ( Round to nearest whole number )
