How do movies and statistics counter work?

I watched the movie : 美 少女 危机 , added a mark about viewing in the application . Since the length of the movie is not specified on tmdb , 0 minutes were added to the viewing statistics. After half an hour , I added the view duration to tmdb and changed it to 90 minutes . Seriesguide will react to tmdb changes ?

Yes, though it might take some time (data is cached on various levels).
