So for fun, My TU Vantage 3.0 score was 695 yesterday and I paid down a card from 50% UTI to 28% UTI and they changed my score to 683 citing that my number of accounts above 50% UTI decreased by 1.

Conversely, MY Experian FICO 8 score went up 14 and all my Experian scores increased form 5-16 points.
