BlueCrab,
I don't think the term 'ligature' is limited to slip knots.
The forensic eveidence contradicts this, since no marks from the ligature were found on JB's wrists, and there would have been marks if she had been strung up.
Ok, so there was a 15.5 inch space from one wrist ligature to the other. Still plenty of room for the victim to move her hands.
And take a good hard look at those wrist ligatures, BlueCrab: they are a joke. One had already come off, being too big for the wrist, and the other was tied
on top of the sleeve with a knot probably so loose that pulling at one end would immediately have caused the knot to come apart with no effort at all.

It is even more obvious in this photo:

The "double loop ligature" looks exactly like a simple shoelace type knot. I think even laypersons can imagine what happens when you pull at one end of that "sophisticated" knot: it gets undone in no time.
If JB had died from ashophyxiation first, no bleeding and swelling in her brain could have occurred. But since both were present, the forensic evidence indicates that the head injury came first. Even die-hard IDIs on other forums (CourtTV's Crimelibrary for example) have come to realize this.
