I heard once that individual revolving CL's over a certain $ amount get partially or fully removed from the formula.
I wanna say 30K.
Nothing to do with overall CL's.
Interesting but there are a lot of people with scores above 760 with 10, 15 and even more open revolving TLs. Are they suffering, no but one has to wonder if they closed all but 5 accounts would their scores be near 800.
From the various and limited disclosures that FairIsaac has made about their secret and proprietary modeling, % util is far and above the most important. Clearly, 30% (revlov + install). But with %util being equal, they aappear to then frown upon more than 5 revolving CLs open. Dont know why, but that is what they say in their posted Powerpoint presentations.. More than 5 CL's open seems to concern their model, but the %util seems to remain linear. Three to five revolving seems to be smiled upon, but more seem to cause their bits and bytes some concern. Just my observations from what FairiIsaac has posted about their modeliing, and what their simple simulator has shown, over and over.. The reverse-enginnering of FICO scores is almost iimpossible to predict! But it is discernible.20 CL's dont impress their model. Keep it to five.
