Here's what can affect scoring:
Overall util, and it goes by tiers rather than by individual changes. So no change to go from 14% to 13%, but there should be a change if you go from 10% to 9%. Your util has to cross one of these break points. Where exactly these break points are get debated a lot. I'm guessing under (not at!) 10%,
maybe under 20%, under 30%, under 50%, under maxed. Once I moved into the 19+ years score bucket, I got points for moving from 8% to 7%, which happens to be that FICO High Achiever util that you see. I never saw that before going 19+ years.
Individual util, especially if you max out a card (85 - 90% of that card's credit limit.)
Number of accounts (not just CC's) reporting balances. If you can get some $0's in there, it starts to help.
