Hi, my Stats page says that my most watched show is "The Arrow" (with 71 Episodes), but that is plain wrong.
Also thee most watched networks cannot be right.
The default view of the stats page only considers episodes watched in the past month. (You can toggle to the past week, or the past year as well).
Mind that if you've marked episodes as watched in bulk, or imported watch data from a different site, it's unknown when exactly you've watched those episodes. This means they won't count towards the "past week/month/year" statistics. They do however count towards the all-time statistics on the right side of the page.
