Issue: "Find all Posts" not updating

I've noticed with myself (and a couple others) that when you click "Find All Posts" of someone's profile page, the posts haven't been updated for 3 days.

I *know* I've posted somewhere in the last 3 days.....

So, how often do these update? It's the only way I have to check previous posts I've made and kind of important to me, unless I want to start subscribing to every thread I've posted in......which I don't.
