If you think it's so stupid then why don't you come up with a better model and put them out of business?
Quote from bigarrow:
True but the FICO is a screwy way to measure credit as the example above shows, 680 was 1/2% lower loan rate than a 679, stupid.
Also when people cancel credit cards that lowers their FICO, again stupid.
Sometimes having a very old bad credit mark on your report removed lowers the score.
