Firstly, Roo's remarks about superfluous successive bights/tucks point
to a fundamental problem that needs to be solved in order to get the
desired slip-free (or merely quick-release) structure: moving the slip-tuck
out *line* of the heavy loading. The typical chain of bight-within-bights
e.g. boils down to, at last tucking to be slipped untucked, something
that could well be solidly bound by great pressure -- a failing with a great
many supposed easy-to-untie solutions presented in the literature (prime
example is the Constrictor), as esp. in much cordage the fold of the bight
tip presents an effectively greater bulk to the compressed twin strands
which will nearly preclude pulling out, or require excessive force, perhaps
to some damage of the cordage -- YMMV.
In any case, Roo's concern is at the base of this issue.
Andy's structure does seem to work around this, at least fairly well (again, YMMV).
I'm trying to come up with a solution that uses one of the cod-end knots, but so far am short of that.

The cod-end knot looks interesting as well, if this is what you're referring too: http://notableknotindex.webs.com/codendknot.html
No, that's unnotable. There are various such knots, but to the point above,
there is a general design that works well. See here, and note how the slip-tuck that
is heavily nipped by load of the binding itself nips --by SET force (i.e., no more than
what one sets it to, not increased by structure loading)-- the ultimate slip-tuck; when
the slip-tuck is pulled out of its nip, it just unwinds its binding of the folded (double)
bight that has strongly nipped the nipping bight that held the slip-tuck -- no matter
how hard that force was, the exterior wraps just fall away, and the loaded bight
is freed, that inner slip-tuck qua
toggle left to fall out! THIS is the neat answer.

hitching question.
Still don't see a statement of purpose for the knot -- of what object is intended to be so hitched,
and by what material under what sort of loads. Since the slip-free aspect requires that one pass
a bight around the object, some structures which will work by repeating this sort of thing can be
material-expensive with a large object (though work fine around a ring, say).
I've used my version for a couple different things, originally I designed it to tie up hammocks.
The slip-free requirement was a deterrent when other people were using it and wouldn't get up.
Huh? You mean, "Hey, lardbutt, move it, MY turn!" "No way, Jose', I'm stayin' put!"
"Okay, then
you're going DOWN!! "
-- and, tug, slip-free, whoosh...
>>> WHAM , and the recalcitrant recliner is realigned with reality -- body slammed! ?
(And we are become accessories to the actionable knot use?)
tsk, tsk!
