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.
Series 1 tested with 5 before the 6 order locked. Series 6 ran long to close the story at 7. No webisodes enter the rows. Only BBC broadcast series episodes are counted. That gives 7 entries for full 6 series coverage. Hastings episodes count the same as Fleming ones in the method used here. The finale aired as one hour but follows totals.
