Just go around to checking my experian fico 8 again. I added a bunch more amex cards. My AAOA went down from 6 years to 4.9 years, my total credit went from 250ish to 650ish. The one other big change was one of my cc went from 70% usage (15K/23K) to less than 10% (1k/23k), and my Experian fico 8 went from 789 to 808.
