Lets be real..Not every 18 hole round can be played in 4 hours or less
Would be nice but not realistic.When you head out you should have mind set of 4 to 5 hours if played in 4 Oh Great! if not Oh well that's the way the round went.If your going to be upset throw a fit then you shouldn't play.
More times than not you'll be disappointed.Why drag down the rest of the group just enjoy the round and your friends
