Ok, what am I not understanding here?

If they are only counting a view as over 3 seconds. And then only averaging the those views what is the problem? They tell me 1000 people viewed it (over 3 seconds), and then say the average view time was 10 seconds for those 1000 users. How is this an issue? Why do I care that 9,000 people scrolled past it and weren't counted in the viewer numbers? Now if they were reporting this as 10,000 viewers and saying 10 second average, I see the problem. Is that what was happening? Or what am I missing?
