Reducing engagement data to 0/1 would lose a lot of precious data, it treats getting 50s through a 1m video worse than watching the whole of a 5s clip, and watching a 2s clip the same as watching a 2s clip on loop 20 times because it's so incredible. Given the point of the app is to get people on it for a long time, it would make much more sense to track number of seconds watched and train to maximize that.
