I revisited this loop. I didn't like it too much the first you posted it. However, when I dress the final tuck more like a bowline, I like this knot better. Unlike your pic, I don't overlap the final tuck. If you dress the knot like I described, then you still have technically the same knot.
By the way, a common rule of dressing is to use the simplest form possible. In your pic, the extra overlap of the working end appears to be unnecessary complexity. Is there a reason for that overlap?
Again, I like this knot when the working end is dressed more like a bowline at the final tuck. When dressed properly, there are some opposing forces in the knot that prevent a full seize up. Thus, I placed this knot in the non-jamming camp.
Advantages:
-No pre-knot
-Non-jamming
-Standing end does not pull on a 1-diameter turn
-More secure than Bowline (maybe)
-Relatively easy to tie (e.g., easier than Zeppelin Loop)
Disadvantages:
-No known history
-More difficult to tie than Bowline
