Granny Scuba,
The objective is to make sure the belt is secure on your body. By hanging the belt perched somewhere above the largest part of your lower abdomen it will not fall off if you find yourself in a heads up orientation. On the hips, above the hips, above the waist, whatever works. Most dive texts books are not written by technical writers so focus on the concept.
Be aware that a wetsuit will compress as you descend. This will have the effect of loosening your belt. Should you go heads up at depth it is possible to have the belt slide right down off of you. This leaves you positively buoyant and if someone does not react fast you are going for an uncontrolled ascent. We hear of this most often with very lean males.
To avoid this problem:
1. Wear your belt high enough that it is perched on something.
2. Tighten it more than you would think comfortable, it will be fine once you go horizontal in the water.
3. While horizontal on the surface check the belt again and tighten so it's snug but still comfortable.
4. When diving deep carefully check the belt for looseness. Adjust the belt or your behavior accordingly.
If you lack a defined body place for the belt to perch get a harness that goes over the shoulders like a DUI Weight & Trim and be done with it.
How it all fits with your BC also needs to be considered. this will get into your torso length and BC size and style.
WFIW I advocate wearing all of your weight on a belt or harness. Except what may need to go higher up in your BC to establish trim. Trim is a level swimming posture while diving. Your body is a see saw. Once you find the right amount of weight you will want to play with where to wear it.
