On my TU report I have noticed that the inquiries are dropping completely off after only one year instead of two. Only for TU - EQ and EX still remaining for two years.
Where did you get the report that shows this? If from myfico, then it is b/c the inq will stop counting against your score after one year. If from a free CR, then I say congratulations, b/c it's not supposed to be that way.
For sure, the inqs on myfico will "disappear" after one year, b/c they no longer hurt your score. But, they will remain for another year after that in reality.
