Gratz on the rank. One thing that has always confused me is that I seem to have equal Activity and Post counts. Not sure why but I guess I'm lucky to be 1:1.
That happens when you post very consistently, but less than once per day on average. Most people get 14 activity points every 2 weeks because they post a lot. But if you post less than 14 times in a fortnight (but at least once), then you get only [the number of posts in that fortnight], and the remainder is "banked": you can get it by posting at any time in the future. So every time you post, your activity will also increase by 1 until you're used all of your banked activity.
You have 1274 banked activity points, more than all but 113 users. A lot of people wish they were you.
For fun, here are users with a lot of "unused" activity. Such users often write especially high-quality posts.
