Some comments on the rankings. Tournament finishes have the biggest impact on your ranking, and more weight is placed on the more recent finishes. If you've played in fewer than 3 tournaments, then your history (win%, playoff%, championships) will factor into the formula. If you have zero tournaments played, then your history has a much greater weight, although there is some regression done to estimate what your tournament results would have been, had you played.
I don't show playoff percentage in the above detail, but it is factored into the formula, which is why greenies is ranked slightly higher than skilly006. rbow923's 44th place finish still has an decent impact on his ranking, which is why he is 11th (although that is up from 18th last year). Your most recent tournament performance gets the most weight, regardless of how long ago it was (see Whiteslave).
