To properly calculate equitable handicaps for players competing from multiple tees, we will apply the directions found in
For these weekend's 2019 Memorial tournament at Royce Brook where we will allow some people to play in RED Tees:
The formula for the course handicap calculation is as follows:
In white Tour Course Handicap = (HI * Whiteslope/113) * 80%
In red Tour Course Handicap will be = ((HI * Redslope/113) - (WhiteCourseRating - RedCourseRating)) * 80%
where HI = HandicapIndex
and for Royce Brook East:
WhiteSlope = 126
WhiteCourseRating = 69.2
RedSlope = 116
RedCourseRating = 65.3
80% is our standard Handicap Allowance
RoyceBrook East does not have published Slope and Course Rating for Men on Red Tees, only for Ladies.
We applied USGA rule 5-2g to temporarily get Slope/CR = 116/65.3.
We extrapolated the chart to account for the difference of 873 yards between RED and WHITE Tees.
(White Tee Yardage = 5935, Red Tee Yardage = 5062, Difference in Yardage is 873)
|Yards||Change in Course Rating||Change in Slope|
So Red CourseRating = White CourseRating -3.9 = 69.2 - 3.9 = 65.3
Red Slope = White Slope - 10 = 126 - 10 = 116
