I've seen on a few player's profiles CTTH scores in the 3000-4000 range for 9 holes. I could think of only 2 possible reasons why anyone would want to do this:
1) To get rid of unwanted balls. But these players are doing this regularly, so I don't think it's for balls. If I wanted to get rid of the balls I would just choose a water hole and put them all into there, so 9 shots would be 9 lost balls.
2) To get more xp. I tried a few games, getting different scores (but not so high), but I only got 14 xp every time, so I've figured it's not for xp.
Anyone any other ideas why you'd want to score in the thousands in CTTH?
