Somehow my CH13 fell off 2 months early, maybe because I disputed it a million times! It was supposed to fall of in July, but I heard sometimes they go ahead and delete a bit early.
My score was 699 last time I checked in late March. With the CH13 deleted, it's now 791!! No other significant changes to my file other than a new target account, which would actually lower my score a bit. I'm thrilled! I don't know if I should check TU or EQ just yet.
