Is there a way to tell if people are seeking out the same video or or if they are watch it because it was suggested? Especially when 90% of the recommendations are repeats?

There isn't even an "I've watched this" or "don't suggest this video anymore" option. You can only say "I'm not interested" which I don't want to do because it will seems like it will downrank the entire channel.

Even if that is the case, I rarely watch the same video, so the recommendation engine should be able to pick that up.
