Thats right, Sounds irresponsible but when I tell beginers how to tie their climbing hitch i just say "wrap and twist it around the rope some kind of way, doesnt really matter too much how... long as it works."
Its pretty hard to tie a hitch that doesnt work as long as there is a few wraps going on with a couple of twists thrown in. Its too complicated to be like "this is a swabish, this is a distel, this is a tk, this is a michoacan, this is a vt, this is an xt, this is a howard.... I have noticed very slight differences in the function of all these hitches. whatever catches is fine by me.
