Thanks for the explanation, I understand the situation a bit better.
But, with your explanation and my current situation, we can see how the ranking/tier system has failed. My actual skill level is not at the master level. My avg has fluctuated anywhere from 68 - 72 for the last four weeks and I've stayed at Pro. Good, that's where I belong. All of a sudden, I shot an amazing -5 and I immediately get switched to Master. Well obviously, my avg rises back to 69-70 but my skill level is still Master. Here is the error: for those who don't sandbag, or even play in tournies, they're getting put into a bracket they don't belong. I know I know, there's no way to differentiate between who's sandbaggin' and who has a real avg, but that's the problem right there. If I continue to shoot an avg between 68-72 over time, WGT should lower my tier back to Pro, regardless of the loopholes of sandbaggin. Just because my avg dropped below 68 because of ONE amazing round, and it was amazing, that shouldn't drop me permanently in a different bracket.
Now if I shot below 68 for 14 games, then hell, lower my tier. But, as it is, I am a lil chihuahua playing with the big dogs.
