The distance the hips turn is related to the distance the shoulders turn and does differ with individuals, I have a fairly powerful frame but can turn my shoulders by around 110 degrees.

I think the hips should be allowed to turn to their natural supportive position in the backswing and the potential energy available in the downswing is related to the amount of shoulder turn and not coiling between the hips and shoulders, or not to any great degree.

If you wind a spring and let it go it will fully uncoil, if you extend an elastic band and release one end it will recoil, the muscle system in the body does not really react this way, Just take yourself into the backswing then let go, you will not rapidly uncoil.
