Right on - that is the spot that you want to hit. TFOX said "I always aim for where I think the path of the arrow will end up going thru the vitals,from a stand this will be slightly higher than from the ground." He is totally correct, but don't misinterpret the verbage "slightly higher". What he means is that the "vitals" picture will move up the deer. If you think about it as hitting the 12 ring on a 3D target, you will hit low and possibly not hit any vitals.

Like TFOX others have said, think about where the arrow will exit and the path it travels to get to the other side.

I carry two judo pointed arrows in my quiver so that I can practice shooting at a leaf or other object from varying heights and distances in tree stands.
