HOW THE HANDICAP INDEX IS COMPUTED

 NUMBER OF ROUNDS IN 12 MONTHS HCPI 05 or 06 Best Round Differential 07 – 08 Best Two Rounds (Average Differential )      (0.96) 09 – 10 Best Three Rounds (Average Differential)    (0.96) 11 – 12 Best Four Rounds (Average Differential)      (0.96) 13 – 14 Best Five Rounds (Average Differential)       (0.96) 15 – 16 Best Six Rounds (Average Differential)         (0.96) 17 Best Seven Rounds (Average Differential)   (0.96) 18 Best Eight Rounds (Average Differential)     (0.96) 19 Best Nine Rounds (Average Differential)     (0.96) 20 or More Best Ten Rounds (Average Differential)       (0.96)

DIFFERENTIAL = Score – Course Rating) x113 / Course Slope
AVERAGE DIFFERENTIAL = sum( differential+  differential …) / number of best rounds
HCPI = verage differential x 0.96

EXAMPLES

1.       Golfer A plays 6 rounds and his best round is a score of 86 from the white tees @ Keeton Park G. C.  Course Rating (69.6) and Course Slope (117) from the white tees.

Differential   =  ( 86   –  69.6 )(113)/117    =    15.8   [  HCP (86)       HCPI (15.8)  ]

2.       Golfer B plays 17 rounds from the white tees @ Keeton Park and his best rounds are scores of 81, 82, 84, 85, 86, 87 and 90.

Differential  1     =  ( 81  – 69.6)(113)/117  =            11.0

Differential  2    =  ( 82  – 69.6)(113)/117  =            12.0

Differential  3    =  ( 84  – 69.6)(113)/117  =            13.9

Differential  4    =  ( 85  – 69.6)(113)/117  =            14.9

Differential  5    =  ( 86  – 69.6)(113)/117  =            15.8

Differential  6    =  ( 87  – 69.6)(113)/117  =            16.8

Differential  7    =  ( 90  – 69.6)(113)/117  =            19.7

Average Differential  =   [ 11.0  +  12.0  + 13.9  +  14.9  +  15.8  +  16.8  +  19.7 ]  / 7  =   14.9

HCPI  =    Average Differential     times   ( 0.96 )     =   14.9  x  0.96     =   14.3

HCP     =    Average Scores =   81 + 82 + 84 + 85 + 86 + 87 +  90/7        =   85
