Yeah, me too! I know I don't weigh anywhere near the breaking point, even when I'm moving about in the hammock, :D:D

The point where the non-tapered bury comes out of the core is weak because the continuous braid is interrupted, there is an inflection and a pinch, and the strands do not work together as well as they do in the normal braided standing part.
IOW, the transition from buried splice to normal braid concentrates stresses. At other places, stresses are distributed more evenly along the line.

Yes, thats what I meant to say.
When the load on rope AD is greater than the capacity of deformed rope segment BC, the rope breaks. :rolleyes:
:sleep:
Usefull for a sheave, but doesn't each side of an eye or loop only have to support half the load? If the bend only reduces the strength to 50% or more than i dont see how it has effected the breaking strength of the rope. It should still be 100%. A sharp bend creates a fatigue point so it might matter in use over time and be important as the rope weakens there, but thats a more complicated test.
You do have to make the eye at least 3 prefably 5 times longer than the diamter so that the two legs dont connect to the splice at a wide angle.
Depending on the size? What sizes is 80%? The 7/64 is small and it has a smaller number of strands(8) than the other sizes. I wonder what the break strength reduction is for that and also how many fid lengths of bury are needed for the adjustable and locked brummel ends of the whoopie sling in 7/64.
Testing D:d would be useful in understanding the behaviour of HMPE (the plot in the link is for wire rope, and I'm told the performance of HMPE is likely to worse).
Of course, a spliced eye (close to twice the strength of a single line) can tolerate significant loss of strength efficiency before falling below the strength of the single line, but a line passed round a sheave/pin/toggle and loaded on both legs cannot.
In short, it depends how one uses the cord.
I use dynaglide slings , been ok so far.
