Not sure if it matters, since it's a FAKO score, but my statement pulled yesterday for BofA and was also reported to Experian. My score jumped from 637 to 650. Maybe because my util was reported at 10% this month??
30% down to 10% helps almost anyone, unless they have horrible recent derogs or something similar.
Congrats! I'm sure your FICO's are paralleling the FAKO.
