> quality of impressions their ads received My understanding is that they only counted it as an impression if it was a view for at least 3 seconds. If anything, including non-impression views is lying about the quality of impressions their ads received, because they're not impressions. I don't know if that's how video ad impression data is normally reported, but it sure sounds more intuitive to me.
