One more picture here.
And yet it has - a soft pillow, for the believers ( and the ignoramuses of the many much better secure bowlines ), to sit on ! 
Could you let us know the working load limit of the rope you are testing?
Roo,
The Bluewater safe line is 7663 lbf minimum breaking strength,
the soft rope is 3000 lbs. breaking strength and 300 lbs. safe working load.
謝謝 alan lee
If you take 1/5 of the 3000 lb as the safe working load, it’d yield 600 lb. So it seems all the loops you’re testing recently are performing well.
Of course ! Go to sleep now - but, be careful, do not sleep only 1/5 of the time you slept last night, because, if you do it for long, you would nt be able to write so interesting things as this !
The idea that anything we say, has to be true only for the 1/5 th of everything, is a solution to my country s debt problem, but it is not a cure for ignorance, I am afraid.
P.S. Whoever believes that things actually do, or should better do, the 1 /5 th, only, of what they can do, and given that "… an aircraft with an overall safety factor of 5 would probably be too heavy to get off the ground ", he should only travel by car - and because cars would presumably obey the same rule, so they will not go faster than horses, he should better find a nice horse, and gallop straight back to the dawn of civilization - a prudent thing to do, indeed, for us all ! If my sailboat s ropes were 5 times heavier than they actually are, I would had been dead and buried ( in the sea, i.e., eaten by the fishes ) a long time ago, because it would had sank - but I suppose THAT would be a good thing for everybody who tries to sell this low-quality merchandise, the fake, so-called “Zeppelin loop” - which, although its quality is the 1 / 5 th of the quality of any of the many safe bowlines, it is attempted to be sold at 5 times the price it deserves !

A knot that jams at the 1 /5 th of the rope s strength, and breaks at the 1 / 5 th of the rope s strength, and slips at the 1 / 5 th of the rope s strength, does almost the 1 /5 x 1/5 x 1/5 of what a 100% knot could do - so, its REAL valueis, say, about the 1 /125 of a 100% knot s value ( that is, it is almost worthless ). Of course, no knot ( not even the fishing knots ) simple enough to be practical can achieve this ideal 100% - but if one is content with less than 1% of that, he should better go back to pre-history… galloping, if necessary !
