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
