Regardless of the length of hair or the length of the cord, I can see where the hair could either be caught or not caught in the knots depending on how closely it was held while being wrapped around the stick and tied. And either way, it isn't proof that it was tied before or after she was dead or unconscious, strangled or not.
That's true. But since I don't see it as proof either way, I don't understand why you keep trying to insist it means something based simply on what you think you see in one photo. Instead of it coming down to you and I simply having different opinions, I'm going to go with the ME who actually saw it himself on her dead body, removed it, was able to examine it closely from any angle he chose (not simply looking at a single photo), and then wrote:
"Blonde hair is entwined in the knot on the posterior aspect of the neck as well as in the cord wrapped around the wooden stick."
