SW checks daily for things that might hurt you --new inqs, changes in addresses, missed payments, new collections. It checks weekly for other things in general that would affect your score, like moving you into a new mortgage rate tier.
There are some built-in delays: good stuff has to update to your CRA's, the CRA's have to report it (EQ is back to being pokey again), the CRA's have a couple of days delay in routinely updating to SW, and then it depends on where SW is in the once-a-week check.
One thing that makes absolutely no sense to me at all is the whole "target score" thing. Despite the way it reads, I have been told by customer service and by others that you should set the score to where you are right now, and that way you will get alerted when it moves away from that score.
That is completely bizarre, but I found that it works. So whenever I get an alert, or when I pull scores anyway (I go through score pull withdrawal pretty often), I make sure to reset the target to that new (current) score. Weird.
