<prompt> Human: The Letters:Equifaxnbsp;Even though its from 1997, I personally found the letters interesting and enlightening. I also commend the man on his persistence and at the same time found it pretty funny.nbsp;A man spent over a year going back and forth with Equifax eventually working his way up to the Board of Directors trying to get his question answered: To attain the highest credit score in the score Equifax produces for conventional mortgage loan underwriting, the Beacon, how can I tell what is the right number of bank revolving accounts?  <response>: Im not educated in those matters, but I would think that the formulas used to compute credit scores are trade secrets that are not easily revealed.I think people get obsessed with credit scores because they represent something unique about a person, but the rules of the game arent fully revealed. I dont think there are many other things like that in life.
