How to use it
Pick two entries and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. One box holds a count of the first entry, one holds the matching count of the second, one holds total episodes. Try the full series against the shortest season.
Season 3 earned 20 after ratings held, which explains the high point. Later years returned to 13. Pilot webisodes stay out because only series episodes count. No extras enter the rows. Only Syfy broadcast season episodes are counted. That gives 5 entries for full coverage. Will episodes count the same as Magnus ones in the method used here. The finale aired as one hour but follows totals.
