Very nice. I don't like the way overhand knots weaken the sling, fuzz the sling up when I untie them, and are hard to untie after I weight them.

I have been using this technique for awhile now; nice to see some real test data on strength.

As to an "official name" - I have seen two reference sources to this or a similar knotting scheme:

Topher Donahue, in his two books, calls it an "adjustable hitch"

Rocorescue has a video showing what they call "webbing shortening technique"
www.rocorescue.com/roco-rescue-blog/tag/techniques/page/2/

Rocorescue shows doing this with a double strand basket hitch, but it can easily be done with just a single strand loop of webbing.

Obviously, this technique can be used to adjust the length of anchor arms at a trad belay or when using very long tied slings when setting up top rope anchors.

I'd be curious to see how it affects peak load on the anchor when tied in nylon.

Correct me if I'm not seeing this correctly, Jim, but I'm pretty sure I've seen/used this one before. Isn't it a standard slip knot with an abnormal loading configuration?

Guideline #1: Don't be a jerk.
