Hopefully somone that knows more than me will come along soon, but I'm pretty sure it's dependant on when your Centre actually submits it. For instance at our Centre they say once a fortnight which gives them leeway if they have a crazy week and don't get it in. I'm guessing 'it' is the attendance records? That's just what I've heard though, I'm on quarterly so can't speak from personal experience. Hope it's through soon!
