Good find Luca!
I had wondered if the sailor's hitch (the 'tied to it's own standing part' version) was in ABoK or not and this is it!!

Oh, and you don't have to bend the standing part. I just drew it that way to make it extra clear of where to insert the tail.
Now I see that other people are calling this knot a "Grapple Hitch" and are using it like an adjustable Gripping Sailor's Hitch only without the extra turns and loading it from the wrong direction. It's no wonder many people have dismissed this knot as slipping too easily, myself included (when initially trying it out for that purpose, long ago).
Previously, I had experimented tying this hitch forward facing and reverse facing to the hitching ring or binding object and determined, imo, that tying it the way I depicted above made it easier to untie after loading.
Also, I feel I may have overstated the title "simplified tying method" in my first post, as it really is the same way as roo's website depicts, just from a different perspective I suppose. Well, it makes it clearer in my mind anyway.
It's encouraging to see that Mr. Ashley himself wrote nice things about this knot.
Thanks Luca!
