In designing above hitch, i carefully maintained the pure inline mechanic.
In fact started it as an example of the properties applied.
(seeking short friction hitch, with 'clean profile' like Bitter End coming out top/along Standing Part, not exiting at right angle
.
Below are 3 pics of probably smarter, richer folks that have been able to give more to these arts than i.
BUT, i think the projected angle of pull on loading (guess that doesn't deserve an acronym)
would be mechanically incorrect; excuse me perhaps should say not as mechanically purely correct..
These work...mostly, but might not on a bad day; they simply, don't seat as well mechanically.
ALSO, as a compounding fault, 1st 2 pics shown rope DOES NOT choke around 360 degrees,
>>some of rope is pulling open; this is even more so exaggerated with wrong angle of pull(shown in 2nd pic).
>>Preceding Half Hitch would give more than 360 degrees grip and be at correct loading angle
>>3rd pic /Round Turn does go the full 360+ choke, but pulls at wrong angle when loaded.
.
When this Running Bowline is loaded, it won't seat into the log inline, it will pull at leveraged angle;
-part of Bowline where standing meets eye will pull way from, not into the log!
.
.
This does show this pull would come from below convex imperfection for better lock on log.
-IMHO best is Half Hitch or Marl to correct angle of pull on Bowline, have more than 360 degrees choke and always use such imperfections when can!
(sometimes even cutting small humboldt opposite Standing Part pull, and then bed line into notch)
Also , see the pull open on Running Bowline by Standing part would be maximum where the helping imperfection/swell is
>>so partially rope can start to ramp over swell when closes; would lock into swell most positively if swell on bottom 180 from Standing Part pull
>>where line seats tightest into log(thus where i putt humbold)!

Timber Hitch pulled inline to spar, same errant angle of pull on otherwise positive mechanic.
See and FEEL where Standing Part comes into Eye part of rope is pulling way from/not into spar
Some logs dragged like this can bounce around like a wildcat refusing to be dragged to cage;
-But slip the preceding Half Hitch over nose and same wildcat now pulls tamely!
-w/o Half Hitch, mechanics (hitchpoint and log center of gravity )fight each other, causing log to not pull 'tamely'
.
.
Clean and simple Round Turn + 2 Half Hitches (1 as stopper, 1 as keeper of stopper);
Resolves some issues, for now the whole circumference of the log has rope tension(previously not seen in 2 above examples).
BUT, still should train eye to not like; as line would load along spar, not at right angle to (unless at balance point)
Proper angle of pull will be across spar as shown, so rope stays inline to itself, for rope only supports on inline/not cross axis.
(when log cut/hangs it will be inline with rope, and hitch leveraged against self angled across host spar like above pic of Timber Hitch.

Friction Hitches Arbos climb on;
are inline pulls on a column of rope, so all have a preceding half and or 'sock'/ rat tail set of braids down column of line
