To my knowledge the higher the score the higher the drop. Lower the score the lower the drop. In no way am I trying to be rude, but in your signature it says 561. I am assuming it is because it had less of an affect combined with other things.
Since I have such a minimal amount of accounts (2), I was just assuming with other peoples recommendations and knowledge it would drop quite a bit for the first few months. Maybe not though. (the fico estimator said about 30-40 points in a possible drop)
