I've noticed that they seem to start prompting more and more rapidly. If I'm binging on a new show, I can start Saturday morning and not get prompted until shortly after noon, say, but then I'll get prompted at 1:30 and then 2:30 and then after the next episode (numbers made up, but you get the idea).
This is really annoying, and the opposite of the sort of smart adaptive behaviour I'd like to see. It'd be great if Netflix could detect, 'this guy seems to have regular work hours (because he normally watches Netflix at a regular time), and appears to be binge-watching a TV show; let's not bother him.'
But then, the Netflix app is still terribly primitive compared to their website, so…maybe I'm asking for too much.
