TimK560: So, based on what you say. Does my avg. have to be saturated?
Yes, that's necessary to be promoted on the "average" scheme...
TimK560: I made TL at 1390 RR. Once I got to 2140 I figured I would Tier up. I guess it's not saturated yet.
Just figure out how many uncharted games you have played recently. And, throw in the occasional "very bad" round, aiming to incredibly high numbers. This might show you if the average is saturated.
