From looking at that list, the only trend I'm seeing is that higher level monks have higher odds of having logged in within the last 24 hrs:

lvl   24hr  total   pct
---   ----  ----- -----
 1    82    26500  0.3%
 2    33    1729   1.9%
 3    46    1023   4.5%
 4    50    676    7.4%
 5    105   870   12.1%
 6    108   583   18.5%
 7    99    330   30.0%
 8    56    187   29.9%
 9    47    100   47.0%
10    190   386   49.2%

I'm guessing that there's probably a difference in the number of post per capita, as well.

So, my real question, about the issue with the quantity of saints (and I say this, after having only hit that level within the last week) -- why is this a problem? Would you rather have a community of people who don't contribute, and thus tend to stay at a lower level?

I'm also going to assume that it's easier to get levels now (my second login was less than 5 months ago), as with a larger community, there's a greater number of people to upvote posts. There's only level inflation if by the time you hit saint, you actually care what level you are. You may care about reputation within the community, and XP may be a measure that has some vague correlation to it, but they are in no way the same.

On a completely unrelated tangent -- as you can get XP for logging in, and then get XP from voting, I'd be interested to know who the highest XP lurker is (ie, never having posted anything)
