I could have sworn I saw one around this site before. I'm having trouble finding it again though. I believe it showed how each factor (aaoa, util, etc.) affected your score.
Does anyone know what I'm talking about?
The log in page posts it.
The chart is not specific as to sub-categories such as AAoA, and is just an overall average.
The percentages, even of the major categories, can vary depending upon the scoring bucket decisions made in the FICO algorithm.
I would not view it as gospel.
