I don't think the scores are updated daily...I'm almost certain of this. If there's a change to the file the score may be run, but if you don't have any changes other than accounts aging over time, I don't believe your score will be updated more than once every few weeks. Keep in mind that in order to determine that there has been a change in your score, FICO has to actually pull your report and run it through the algorithm. Doing this for millions of accounts every day may not be practical. On the other hand, the process should be much more transparent. When you buy ScoreWatch it isn't really clear that the score won't be updated daily, in fact you are almost lead to believe that it will be updated daily.
