I've found event driven changes update and alert much quicker than non event driven changes. Meaning, an inquiry or a new account alert (with a resulting score change soon after) will happen within a day or two of reporting, whereas aging or deletion (since it doesn't trigger an event alert) will take until ScoreWatch does an intermittent check and subsequent score alert.
Case in point: I was sitting at a 645, applied with DCU for a car loan, and they quoted me at 660. This confused me, because DCU and MyFICO both use the Beacon score (EQ04), so they should have been spot on. Two days later when the INQ hit my reports, I instantly got a notification from ScoreWatch for the INQ, and my score updated to 660 on here as well.
