Exceptional Tournament Scores Reported in 2000
HOW TO DETERMINE AN EXCEPTIONAL TOURNAMENT SCORE
1. Take the Gross Score and subtract the Course Handicap to determine the Net Score. Then take the Net Score and subtract the Course Rating to determine the Net Differential.
Example: Handicap Index of 11.5 with Slope of 129 converts to a 13 Course Handicap (Course Rating of 70.1)
75 Gross Score Shot
- 13 Subtract Course Handicap
= 62 Net Score
- 70 Subtract Course Rating (after rounding off to nearest whole number)
= - 8 Net Differential
The odds of shooting a Net Differential of -8 with a Course Handicap of 13 are 1138:1

2. Another way to figure out what scores to report to the CGA is to subtract the Net Differentials in the gray zone from the Course Rating.
For Course Handicaps 0 to 5:
70 Course Rating (round off to nearest tenth)
=65 Net Score Shot in Gray Area
For Course Handicaps 6 to 12:
= 64 Net Score Shot in Gray Area
REPORT TO CGA NET SCORE OF:
65 OR BETTER
64 OR BETTER
63 OR BETTER
62 OR BETTER
61 OR BETTER
The table above gives the odds for shooting a single round net score equal to or better than the course rating by one, two, three, etc., strokes for various handicap ranges. In other words these are the odds that the difference between the handicap differential of the round you played and your Handicap Index (i.e., the "net differential"), is zero, minus one, minus two, etc. Note that 1000 to 1 generally represents a lifetime of golf, or for the avid player who posts 100 rounds per year, it represents a decade of golf.
