dickdarstardly: I don't believe there is a rule saying you have to play a certain amount of ranked rounds or you have to tier up.
But the spirit of this game, like real golf, is to make it clear what a player's abilities are so all players know what they are up against. We are not talking about players that play to their abilities or those that do not have the desire to put in the stick time. Those guys are where they naturally belong and the reason we have tiers in the first place. What we are talking about are players that violate the basic concept of golf by intentionally portraying themselves as something they are not. And since it is almost impossible to police this, that's why new players need to know about sandbagging before they play anyone for credits. After you've been here a while, you are on your own (wink).
