I.e. How much more likely is someone who watches 21 hours vs 20 hours to be retained? Then how much more likely is someone who watches 41 hours vs 40 hours to be retained? I'm guessing that on average there is a much smaller difference between 41 and 40 than between 21 and 20.

I'm also guessing it may turn negative as some people have shown they will subscribe for a month, binge on their favorite/new shows, and then cancel. Perhaps renewing in a few months time to do it again.

Would also be curious about other metrics such as search time : watch time. I'd imaging people spending more time searching and less time watching get frustrated and are more likely to cancel. With autoplay it eliminates searching for some.

I'm also curious why there isn't a setting to enable/disable autoplay.
