Fix time "spent watching" tv shows
No matter what show I watch, each episode adds 40 minutes to my time "spent watching," even if the episode is less than 40 minutes long. The time spent watching should reflect how long episodes are, not just take the number of episodes watched and multiply by 40 minutes. Also, the shows in the "plan to watch" shouldn't count towards time spent watching since I haven't watched them yet.
To get data on every episode to multiply by exact minutes would take a lot of resources and time to load the page will be a minute instead of 1 second. For that reason, we are using approximate calculations based on average episode times.
