i totally agree. i have been observing alot and ive been TRYING to observe how the infamous wind knot forms. i havnt been able to determin it yet but i have a pretty good guess.
i believe what happens is that when youre cast is imperfect, the casting gods try to determine what youre punishment will be. sometimes they just decide to make the fly smack you in the head as punishment, but when they are feeling especially cruel, they will make youre line twist and wrap over itself to create a knot it would take a professional alcoholic to untie.
but thats just my theory
