myfico FINALLY updated my score to be equivalent to what experian showed over two weeks ago, the increase being due to my PLOC reporting.
However myfico didn't figure out it was a new account posting and reported the reason for the change was a "balance increase".
The real reason is the PLOC increased my AAoA when it reported because it is actually my second oldest account but for some reason didn't report until now.
So they are two weeks out of date and their reasons are misleading.
