Daypart Rotation

Daypart Rotation-Period Setting

I'm looking at my song rotation history and I see one song that played in the overnight show about three months ago has repeated in the overnight show this week. This is a category with a very long turnover, so the songs in it only schedule every three months. I guess it happened because M1 can't look back that far for the rule that prevents songs from repeating in the same daypart. Is that right?
