I've never seen the vidoe and also have never had a deer duck my arrow. I aim low on the deer. By shooting 1/3 of the way up the body you'll get a hit if the deer don't mve and if he tries to duck the arrow you'll have a whole lot of lung to catch the arrow for you.

I have in the past shot over deer but I'll take the blame on those shots. It wasn't the deer ducking that caused me to miss. Usually it a bad estimate of distance that takes it's toll.
