I have a question that I was hoping for help on. I need to make a label for a running 26 week report that I create in excel. It compares sales this year with last year. However, my labels 2005 vs. 2004 are not completely true, because in all reality it is 1 week of 2005 with 25 weeks of 2004 compared to 1 week of 2004 and 25 weeks of 2003. Does anyone have any suggestions for what I should label this to accurately represent what it is showing?

Thanks in advance!
