To properly calculate equitable handicaps for players competing from multiple tees, we will apply the directions found in
https://www.usga.org/HandicapFAQ/handicap_answer.asp?FAQidx=6
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 | |
| 693 | 714 | 3.1 | 8 |
| 715 | 736 | 3.2 | 8 |
| 737 | 758 | 3.3 | 8 |
| 759 | 780 | 3.4 | 8 |
| 781 | 802 | 3.5 | 9 |
| 803 | 824 | 3.6 | 9 |
| 825 | 846 | 3.7 | 9 |
| 847 | 868 | 3.8 | 9 |
| 869 | 890 | 3.9 | 10 |
| 891 | 912 | 4 | 10 |
So Red CourseRating = White CourseRating -3.9 = 69.2 - 3.9 = 65.3
Red Slope = White Slope - 10 = 126 - 10 = 116
