Well I made the mistake of dumping rounds in which I had no hope of getting the score I needed and only posted a bunch of low scores. I was "upgraded" to the Master tier and can't begin to compete. Hopefully I will be kicked back to the Pro level where I belong (maybe). Does anyone know if players move both up and down based on play?
No, unfortunately you never move back down.
That's the downside of not posting those bad rounds.
