You need to have alot more 18 hole tournaments and less 9 hole tournamnents. It seems like that you have more 9 hole and less 18 hole.
Why?
Obviously I don't have access to the figures but I would guess it's currently based on the time that people are logged on to and playing games on the site. The average person probably will pop in here and play a 9 hole round but doesn't stick around long enough to play 18 nearly as often. Currently there is a side benefit for those of us who attempt to finish every round we start. The 9 hole option is nice in case we start with a bad 9 holes. Instead of quitting or being relegated to playing a meaningless back 9 we can just enter another tournament.
I am not saying that is a bad thing, all I am saying is that it should be more even than it is, That's all.
I would like to see more 18 hole tourneys as well but the current ratio is probably based on someone crunching numbers in their accounting office.
