The reason why i think this:
Members: 4,065, Active Members: 1,378
So the percentage of active members in comparation to total members is about 33.9% (wow, can i do my math
).
There are 129 pages on the member list. 33.9% of the 129 is about 43. So when your on page 129-43=86 (at least, if you start with 0 posts on page one) you see the sudden twist from 9 to 10 posts. (see this page)
So, that's why i said that, it seemed the most logic explaination. But maybe the mods know better?
And no, i'm not going to check all the 'last logged in date' to see if that happends to work out too
