52 weeks ago today isnt the same day as today - it can be offset by one or two days.  So for example when I compare the performance of Sunday Feb 14, 2010 to the same Sunday last year that would be Feb 15, 2009.  If your business is cyclical on a weekly basis then the day shift has to be done outside of sitecatalyst.
