I'm not surprised that in exercising mastery of clip-and-comment that the previous poster left this out from my post:
Plain enough language. Since the cordage in the sleeve is larger than that of the bury, the starting point I suggested is conservative, a longer length, and then it is just a starting point.
It would not be hard for someone regularly working with cordage to bury a piece of say Dynaglide with nominal diameter of 2mm or ZingIt of 1.75mm within another length of 1/8" (3mm) Amsteel blue. How long the bury? 72 x 3mm =216mm, about 8 1/2", whether with Zingit or Dynaglide. Stitch to keep it from slipping, and apply an increasing load approaching breaking strength line, in line with the splice. Record the load at which there is failure, and whether by slippage or breakage. If by breakage, then the bury was long enough. If by slippage, increase the bury. That's what the word trial means.
Quality polyester fiber and the cordage made of it averages about 1/3 the strength of Dyneema / Spectra /UHMWPE weight for weight. Sure, there's variation for quality and braiding characteristics. But, for figure of merit, 1/2 is too large and 1/4 doesn't credit polyester enough.

I did snip that out. But not intentionally. Sorry bout that.
I also have a question on splicing. I've eye spiced loop in 1/8th inch 12 strand amsteel according to sampson's instructions found here and am quite comfortable doing so:
I just received some 7/64th inch 8-strand amsteel from Dutch and want to do essentially the same thing. Are people splicing with a bury just like you would with 12-strand amsteel, or are people using a different technique as described by Samson here:
The reason I ask is because my 8-strand amsteel doesn't really look the way that Samson describes their 8-strand class 2 (dyneema) rope, which is "made of
8-strands grouped in 4 pairs" per the instructions in the second link above.
Feebus, I sent you a PM with links on how to do it.
alrany187: Can you please post the links here? I also recently received some 7/64th" amsteel from Dutch, and would be very interested in looking at the links on how to do this. Thanks!
I have abandoned brummels when splicing. I simply put a few hand stitches in the bury to prevent slippage when unloaded. It just seems simpler to me.

Excellent! Ellis I used the instructions provided in your links and finished my project. Thanks for your help. As an aside, I found that I was able to use the method that uses both ends despite the one end already having a loop in it. Basically I was able to pass my looped end through the split in the cord because I was able to split it wide enough. While the whole reverse loop looked doable, I just figured I would try and pass my loop through the split and it worked.
