CSS is calculated as follows:

1. Discount all scores returned by category 4 players (handicaps 21 to 28)

2. Calculate the percentage of players who competed in the competition in each of categories 1, 2 and 3

3. Calculate the percentage of scores returned by the category 1, 2 and 3 players which were two over the Standard Scratch Score of the course, or better.

4. Use the percentages from (2) and (3) to determine the Competition Scratch Score by referring to a table supplied by CONGU for the purpose.

In your specific circumstance, the CSS will probably rise when all the NRs have been properly entered.
