My question would be if that deer was hit where that hole is, it should have been down and able to be shot again before the shock wore off and it could get up and away. If you look at the carcass that WB put up, there is meat between the bottom of the spine to above about the 7th rib that can be hit and result in an animal getting away to recover, especially with an arrow that doesn't shock like a bullet does. A little higher and you're into the spine for a knockdown where they can't get up. A tad lower and you're into the heart/lung area just forward of the paunch, which should result in a dead animal pretty quick if it's a double lunger. If it's a one lung hit, especailly on an elk, they can go a long ways and be hard to recover.
