Joel, there is no hard and fast rule about it. Much of it depends on how the bow's grip is formed. How thick, how thin, if it's formed centered on the axis of pressure from the draw oroffset/angled to one side or the other...

Another bunch of it is how your hand is formed. Long and lean or short and thick. Long and thick or short and lean. Or anywhere in between. Even the flexibilityof your wrists can come into play. For instance, your low wrist might be lower or higher than my low wrist, depending on whether your wrist bends more or less than mine does. All play a part in how your grip fits a certain bow.

Bows are all different and we are all different. In my hand, most bowslike to ride centered just to the thumb side of the lifeline - maybe about a quarter of an inch - and that's where I'd like all of them to sit when I'm shooting. But not all do.

Sometimes you just gotta use a loose grip, grab the handle however is comfortable for you and let 'em torque, and hope they torque the same way every time. A tight, whitekucklegrip on a bow like that will keep it from torquing the same from one shot to the next.
