Paid off 2200 of a 4800 balance on a CC a few days ago and could not wait to see what that would do for my score. (I knew it was supposed to report yesterday based on a TrueCredit pull a while back.)
Pulled EX and TU this am- and GRRRRRR, TU hasn't updated balance yet!!!! GRRRR! But wait! EX has- and my score has risen from 592 on 4/8, the lowest of my three, up to 611- out of the dreaded 500's! 19 points in 8 days, woohoo! It's now my middle score, which I'm pleased with.
Then I remember one thing- oh, yeah, I'm disputing one of my younger CA's on EX-- so it's probably not factored into FICO right now, thus raising my score artificially.

Oh, well- it gives me an idea of where I'll be if this comes through. They've only got 14 more days to respond, and I did it online so I'll know immediately. (And yes, I printed out the dispute confirmation page!)
But... bottom line, the scores are *up*! I sent out a bunch of GW's again yesterday, we'll see where that gets me. Wish me luck!
