I Absolutely agree. If you shoot a deer lower in the lungs, the bloods fills them much faster and can almost get an immediate blood trail. I also believe that a lower lung shot brings the deers center of gravity down therefor making it fall quicker. My lower shot lung deer have gone shorter distances than the ones I have shot higher up in the lungs. Blood trails on lower lung deer have also been like following a garden house with red water. Upper shot ones seem to not have the amount of blood expelled.
