Your FICO score can literally change daily if you have stuff happening daily. SW score alerts result in your target score being met or surpassed and the monitoring of that score (assuming nothing specific triggered it) happened every 7 days or so. Look at the date of the alert within your alert history. There may have been a lag time of a day or so. Essentially, your FICO increased one day and dropped the next due to something else changing. Look through your EQ FICO to see if you can find any changes and reset the target score to 596 ASAP.
