Big difference between hitting the spine above the shoulder and hitting the base of the brain (medulla oblongata) which is where a shot at the back of the throat is going.

That's why I stated in an earlier post that the further up the neck you go, the more likely it's lights out. As Oaknut posted, hitting the spine further back just paralyzes everything from where you hit and back.
Contrary to what is being posted here by others who should know better based on their own experience, hitting the spine does not equal instant death. It does make for an easy walk up to put a finisher in it though, they aren't going far without use of their hind legs.
The high shoulder shot, as shown in the videos, looks dramatic (especially on animals that top out at 80 lbs) but it's not instant death. Note how the camera is never on the animal longer than 10 seconds or so after the shot. In one video, you can see the deer start to move its head again before the camera cuts. When they somewhat recover from having the wind knocked out if them and laid flat by the energy transfer, they start to expire. That usually takes a bit of time. Generally that's when the cameraman turns to film the high fivin' and back slappin'.
Although it looks like those deer are going to cover some ground in the heart/lung shot videos, they're dead in short order. All those reactions to the shot are exactly what you want to see, and you're not losing both front shoulders of a deer.
If you're unwilling to follow a blood trail for 50 or 100 yards to recover your animal, you're in the wrong sport.
