A Handicap Differential is the difference between a player's adjusted gross score and the USGA Course Rating™ of the course on which the score was made.
The difference is then multiplied by 113, and then divided by the USGA Slope Rating® from the tees played and rounded to the nearest tenth.
Eddy shoots 75 on a par 72 golf course
Golf Course Rating™ is 68.5
Slope is 131
75 - 72 = 3
3 x 113 = 339
339 divided by 131 = 2.6 Handicap Differential
