Sure, it's possible. Less is possible as well. So is more. All depends on the change in the report data. You really have to carefully review reports from before and after the change.

Which scoring model? That can have an impact as well. You don't have just one score for each CRA. Typically for a given scoring model you'll have a score with each of the 3 major CRA's. There are many scoring models used by creditors.
