Ha, I just fiddled such a knot, myself! (I'll need to check
how similar, but similar in the "returning eye leg" going
past the SPart's nipping turn and THEN u-turning to pass
through it, and collar itself. In my case, I've done some
little further tucking.)
Yes, I take the tail beyond your point back through
the tuck (making a larkshead/girth,cow hitch) and
then tuck it through the main nipping loop (giving
3 diameters for that to surround & compress).
I still need to play with it in some of my firmer/stiffer
(less flexible) climbing ropes (an old Mammut? (ca. 1990?!)
& a gym rope) for assessing it's ability to resist too
much loosening.
(That said, since October 2016 I've illustrated my
collection of then-not-yet-drawn(but-in-play-ropes)
knots and tallied over 200 (!) eye knots of 500 total ::
how many could one possibly need?
(Well, among that 200 are plenty that could be tossed
w/o great remorse, but then there remain many decent
things, too.)
)
I'll double-check the Hensel & Gretel reference;
the number "150" must be different from one knot
I've cited of theirs, which is a BS attempted parroting
of the Wot?knot. But mostly they're just BS, nonsense.
(--and through FOUR editions and numerous printings)
Btw, vs. the Capstan knot, I'm thinking that this
"Basko Loop" should be seen as better resisting
the **helical** shape of the SPart --more towards
a "loop" and that structure's better/surer compressing
--a possibility, at least, when dressing & setting.
Which is to concur in SS369's leaning to a surer thing.
