I think there are a number of monks who love to do statistics on trends involving monk rankings, XP, frequency of posts, etc. Alas, I am not one of them, but I would expect someone, at some point, to come up with some sort of summary report, based on some metric that can be reliably compared across that "great divide" in the PM-XP system. It might make for an interesting comparison to self-reported behavior... (or it might end up looking like a random variable).
