I have doubts of its effectiveness
One, many hunters on a deer drive haven't practice the art often, together. It combines hunters of different abilities. All hunters are not the same. That's some of its weak points.
A deer drive doesn't count all deer; some escape through certain imperfections of the hunters. Perhaps the reason for a deer drive in the first place; the basic imperfection of the hunters.
Better hunting, I find, is when the deer is moving and the hunter is stone quiet. That's not synominous with a deer drive.
