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 4 split into 9 plus 12 but totals 21. Holiday specials live inside season totals. No webisodes enter the rows. Only Syfy broadcast season episodes are counted. That gives 6 entries for full 5 season coverage. Fargo episodes count the same as Carter ones in the method used here. The finale aired as one hour but follows totals.
