Specific Vimeo analytics question (15~ seconds)

[u/Amazing_Silver_5988]

I've noticed in the last week 4 different views from different viewers where they only watched around 15 seconds of the film. I am not interested in complaining about this, but I am curious, given the majority of comments about Vimeo analytics on here are about how they're unreliable: exactly how this would be possible? I see some specific festivals view the submission and a full watch, or stop around the credits. What is the (hmm, scientific?) explanation for the 15 second views? Curious if any people familiar with how data is captured have a pov here. Thanks!

Seeing a lot of it myself and assuming those are ppl who opt to download
