I definitely believe that paying subscribers would, on average, watch most of the video. There are popular creators publishing 3+ hour videos on YouTube, for free, generating millions of views from viewers watching most of the content... so paying subscribers doing the same is very much within the realms of possibility.

That doesn't really contradict what I'm saying does it? Are you claiming that most subscribers watch most of the videos they watch? I'd be interested in seeing that stat for 3 hour videos!
