If this is the same derog you were referring to on another thread, it seems likely that EQ is reporting it differently than EX. You said in your other post it was showing a late just 2 months ago - that's a pretty big score dropper and can account for much of that point difference.
If it's reporting incorrectly, you can either dispute it and have it corrected, or wait it out until the drop off date of 8/2007 since it's paid.
