While this video is hard to sit through, due to all of the useless babble, if you watch it from the 9:00 to 10:00 minute mark, You can avoid most of their bloviating and, "get to the good part".
Where they actually time how long it takes to get oil pressure from prefilling the filter with oil, as opposed to installing it dry. They also discuss the fallacy of having the new "dirty" oil from the bottle bypassing the filter by prefilling.
I think prefilling is worth doing. On both my truck and Jeep, (which have oil pressure gauges from the factory), I've gotten similar results. And while you're certainly not going to "damage" your engine by not prefilling the oil filter first, it's so effortless to do, I can't think of a reason not to. Unless it's too horizontal, or difficult to get started on the threads, where as you'll make a big mess.
