Regarding the average view duration %: I think it makes sense for longer videos to have somewhat lower percentages. Fewer people are willing to sit through a long video, compared to a short one, so it is logical to have more people fall off throughout the video. But if you measure the average view duration in terms of minutes, not percentages, your results are really impressive: AI 2027 and MechaHitler have AVDs of ca 10 minutes and 13.5 minutes, respectively.
