as far as calculating average age, does fico use the oldest cc account or your oldest account in calculating your average age for scoring purposes, or does it just use all of your accounts (including ca)? when looking at my cr on CCT, after all of my cr's, it had the comment that my oldest cc is 7 months old. and i know that CCT gives fakos, but this got me thinking. my oldest account is around 9 years old, but my oldest cc is indeed 7 months old.
