I have had this requirement my self several times. The solution depended on what the compare was for. When I needed to identify new work to do, I created an empty first generation. But when the compare was looking for status changes for defined items, I created an empty first generation and then populated it with starting values for the items being tracked.
Your solution will depend on what is needed in the end result. Thank you and have a Terrific day!
