Buff, out-standing video.
I watched it several times in super slow motions (I assume you did also) it looks like you hit the shoulder-blade quartering away, if you where to high your 78lb bow would of blown your arrow through the meat above the spine.
The 1st time I watched it, I thought you got bad penetration on that hog ( Why? )just before the shot he turns his head to the left away from you and his shoulder fallows, he caught the hole thing and he even stumbles from the hit.
The shot needed to be 6-8 inches back at that shot angle, I don't think you hit to high, just to far forward.
Not trying to argue or anything like that, just expressing what I see on the video and giving my 2cents.
