I don't get how this is possible. I have a few videos where people have commented telling me they enjoyed the whole video. this about 100 or so people that have commented this. The videos which they enjoyed have an audience retention rate below 20 percent. I don't understand how this is possible. I've also gotten people that haven't commented directly on youtube telling me on twitter etc they have enjoyed these videos all the way through. One of these videos has over 10,000 views yet somehow is below 20 percent audience retention. the relative audience retention is higher than the average retention.
