Woah this is exactly the kind of information I was looking for. It kinda complements the information that you gather and it's a marvelous data to look at. I'll follow the activity on that thread while I try to thin in other information that could also beneficial to have displayed.
My guess: there's only a 9 Merit window to stay Jr. Member once a user has enough Activity, and there's a 90 Merit window to keep Member rank.
I also see that as a reason, but the fact is that albeit the window is larger (9 vs 90 Merit) one shouldn't feel discouraged in order to keep providing quality posts, or at least try right? Sure one can debate whether or not a particular post is useful / positive as it kinda depends on the user who is rating it and also if it touches some fields that the appraiser also agrees on.
Since your thread tracks the top merit earners in the past 30 days, the window itself, although bigger, isn't enough right? Because what we're tracking is the quantity of merit that is earned in each rank right? Or am I making some kind of wrong assumption?
