I am not saying you are incorrect but the congu advice document just says "For a score to be acceptable as a 9-hole score, all holes of the measured 9-hole course must have been played. 9-hole scores are scaled up to an 18-hole equivalent gross differential as set out in Rule 5.1b. For a score to be acceptable as an 18-hole score at least 10 holes of the measured course must have been played. Scores of between 10 and 17 holes are scaled up to an 18-hole equivalent gross differential in accordance with Rule 3.2."Sorry wrong. Rule 2.2 applies he is playing a 18 hole round not a nine hole round.
