Excuse me Renni, I got carried off topic by some replies.
renniw52: How many of you will start a ranked round and then forfeit it to protect your average?
I full-heartedly agree that this is the most naive and unnecessary reason to quit a game. Due to the nonlinear calculation of the average, those "bad" rounds don't have any importance at all. Play them, get the XPs included and forget them. The experience will eventually help you.
Getting on the real courses may be a humilation sometimes, but on the bright side you may recognise "that you needed it" for some reason or the other. And, taking the risk of it, there may be some extraordinary experience, from the environment, from lucky shots or from some great company.
Priceless!
