Another example of CCID and SJ's point is that my FICO 8 scores have not moved over 2+ - 3 months reporting but my MTG scores, Bankcard and Auto scores have been up and down depending on how many accounts reported a balance. it's actually percentage but I can't determine the exact % other than EX MTG which stays put at 3/12 (25%) and 4/12 (33%) accounts reporting a balance. 5/12 caused a 9 pt dip. Varying dips with my EX Auto 2 and Bankcard 2 with 5/12 reporting (No change to those industry standard FICO 8 scores). However, due to timing of reporting this month my TU FICO 8 dropped 4 points due to 6/12 (50%) reporting but EX & EQ did not change with the same data. I expect TU to recover once the other accounts report and show only 4/12 reporting. So at least above 42% reporting affects TU FICO 8 but does not affect EX and EQ for my profile.
I believe one reason so many people provide data points after realizing there is no blanket answers is since not only the different models yield different result but sometimes even the different CRA. Let alone different profiles and scorecards. Its not made to be easily figured out
