Well, Brett, there are some things you need to be aware of...
- While your average may go up or down, your ranking will not. Therefore, once you move from Am, to Pro... or Pro to Master... you can't go back down. When you are forced to play from further back you will not do as well at first and your average may go back up a bit. I have seen Masters with averages in the 80s because they can't compete from the tips. --- Therefore, it will behoove you to post every score you ever create to make sure that your average is where it needs to be and your rankings will increase when you're ready.
- Having said that, there are people in this game who move to the Master ranking and find that, since they haven't been honestly posting every score in their haste to become a Master using Master toys, they start to suck really bad in tourneys and what-not. In order to make them feel like they actually know what they are doing, they create a new account and become what we know as a "Multiple". --- This is AGAINST the rules and the LYING, CHEATING, SOBs who do it should have all accounts banned and be hung from the neck until dead... (That's just my opinion, though. Some folks aren't as harsh as I am.)
- And finally... Sandbagging. Some folks will do anything to NOT move up in rankings and will throw in a really bad score now and again to keep their averages up and their rankings down. This is why WGT will not publish the averages needed to move from Hack - Amat. - Pro - Master.. If they did, these low-lifes would hang just under the number to enter tourneys to win credits and what-not.
Keep in mind, though, that WGT is taking a pro-active stance on the folks that you mentioned in your message. They will verify every tourney score and if they ~think~ that the score posted is artificially low, (via sand-bagging, multiple, et al) the score is thrown out and the appropriate official action is taken.... (LIKE HANGING THE LYING, CHEATING, SOBS FROM THE NECK UNTIL DEAD!!!!! ..... oops, sorry.)
I hope this helps.
