I have an all-time set, which is based on results of all tournaments. You can only get points by making the quarterfinals or better. It's a cumulative list, so you can't lose points

I also have a current rankings set, which is basically adding together the points from each of the last 6 tournaments. To qualify, though, you have to make it to the first elimination round. If you can't get out of the qualifying round, you get no points. This list fluctuates wildly as people's high point efforts cycle off or a new high point effort get added in. The only major issue is people who don't participate one month get a zero point entry that takes six months to cycle off. So a consistent 4500 point player can get ranked higher than a routine quarterfinalist who skips a month or two.

I'll post the current lists under a new header, and post the updated rankings Sunday after Game 39 concludes for comparison.
