I guess it’s calculated by number of events completed, and not by number of series. Not all exclusive series have the same number of events (varying between 42 and 48 events if I’m not mistaken). If you have completed 11/20 series (55%), but those series have less events then the 9 you haven’t completed yet, your percentage will be at less then 55%.
