No quarrel with larger safety margins. The 1/8" whoopie slings will weigh a whopping 40% more.....on a small base, so < 1 oz heavier. And they'll scare fewer strangers to Amstell with their slender appearance.
But, where does your 40% de-rating for a constrictor come from? It surprises me because specs for breaking strength are explicitly for spliced rope, and constrictor in the whoopie is exactly source of strength in an eye splice, which, IIRC does not bear a 40% derating. To derate implies the location of likely failure his been identified. Is there supposed to be stress riser at the entry or exit of the bury at which the whoopie is supposed to break much earlier than the rest of the line?
Or is it supposed by Samson that whoopies purely in tension will be strapped across a load, and that abrasion can be expected to degrade the cord?

Most all whoopie failures are due to the learning curve. Take time to watch the helpful videos.
7/64 is plenty for me, I weigh over 300 and they are working fine.
Popular size is 6-8 feet in finished length. Add into that the strap length, and you can generally find a spot to hang in any woods.

I have one hammock rigged with 3 foot finished slings, and most of my hammocks have around 5s. The ones we sell finish at about 6 foot.

^ 6-6.5" for your fixed eye, and 10" for your adjustable bury is concidered the standard accepted lengths.
The bury needs to be a finished 10" bury. That means you need to go about 12" in the splicing process to "milk" it back to the 10" finished. I dont think your going to have a problem if it finishes a little below 10".
As far as length, I made mine 8' knowing that I wouldn't probably need that. So they adjust down to what less than 2 foot so that covered my short and long needs. This way I dont have to mess with any extension needs and for the money its really nothing for the few extra feet.
Thats just what I did.
Made my straps 10' for the same reason. Now we got some big Oaks in Alabama so I dont want to miss the perfect spot due to a couple of inches of length.
The weight and bulk for the extra was not enough for me to count. Some may find it an offensive thought.
Good luck.

This stuff doesn't stretch, but things slip on the first load if you haven't cranked them down.
Set up hammock. Load hammock. Get out and re-adjust hammock.
