it's the number your post in a board divided by number of all posts in a board.
so if I have 1000 posts in meta and there are 100000 meta posts in total, it'll show as 0.1%.
Does all post in the board mean all the posts in the board since the forum was created? Or it only takes into account of posts made in a particular month or a time period?
since the forum was created.
oh, and if a board have a sub, the posts in the sub-board doesn't get added to its total posts.
That was my understanding of it. Ie:
I have 5480 posts in hardware
I'm 1.3666% by activity in Hardware.
Hardware has 484,894 Posts.
5480 / 0.013666 = 401,000 posts. Close enough I guess?
