Yes, it does. As long as they`re ranked you should see the difference. CTTH does not count except in your awards. Also, the more ranked rounds you have, the less your stats will be changed by a single round(9 or 18). Furthermore, some of the stats are skewed because a 9 hole round counts the same as an 18 hole round. For example the putts per round ave. counts, lets say 14 putts, as an 18 hole round. There are others but, you can see the ones that are true or not by looking at them. Cheers
