DW's equifax score increased by 11 points (784 -> 785) when she went from having 2 account reporting a balance to 1. Seems like a pretty big jump. Particularly since one of the account reporting a balance early was a charge card (Amex Gold) which isn't part of the Util equation. Her overall util actually went up from <1% to 8%.
Also, one card that is now reporting a balance has individual util of 29%. It seems odd to see an increase of this magnitude.
My Starting Score: EQ: 691 (11/30/11) TU98: 726 (11/30/11)
