Below a hybrid mannequin — during which the primary pulled rating of 700 or greater would function the consultant rating, whereas debtors under 700 would nonetheless require a tri-merge — 4% of customers within the 640 to 659 vary and almost 8% within the 660 to 679 vary had a most bureau rating of not less than 700. That dynamic may shift some debtors into completely different pricing or eligibility classes relying on which report is used, the research exhibits.
