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 5 was cut to 18 by the 2007 strike. Season 9 was ordered short to close the story at 13. The WB to CW move did not reset the count. No webisodes enter the rows. Only broadcast season episodes are counted. That gives 10 entries for full coverage. Nathan episodes count the same as Haley ones in the method used here. The finale aired as one hour but follows totals.
