>I'm suggesting some of this total watchtime is not meaningful (<1 min watch time) and may still contribute to a significant proportion of the total watch time. How does this contribution a significant proportion to the total watch time? Even the last example that had 90% of users not finishing the movie required 87% of subscribers to at least watch some of it. Do you think the number of subscribers who watched even a second of this movie is higher than 87%? >You also assume there are no users with multiple accounts. Do you mean a person with multiple different Netflix accounts or multiple people sharing a single Netflix account? I have no idea why someone would do the former and I would be shocked if there was any sizable number of people who do that. If you mean the latter, my previous comment used the assumption that each subscriber equals two users like you originally suggested. >I think these two assumptions are not very reasonable, and can explain why you find your own estimate "literally unbelievable". Ok, why don't you throw together some numbers on the estimated percentage of Netflix subscribers who watched any part of this movie?
