Strength of dyneema grommets?

[Essington]

I have been making some overlapping dyneema grommets from the working rope book, and in light of the recent soft shackle testing, I am wondering if the two styles of grommets have been pull tested?

What percent of line strength does the overlapping grommet break at, and what about a grommet with a full 72 diameter tail bury?

Do the overlapping grommets get weaker as the circumference decreases?

My guess would be that we should get close to 200% of the line strength, but I have seen no data to validate that guess.

Hello at last,
I finally dug out some old test results on HM grommets. We didn't test many, and the results varied from about 113% to 180% of rated strength. The weak ones were stitched at the crossover, and the strong ones Brummeled. Also, the weak ones had a very short overlap of the ends, so it is likely there was a stress riser there at load. Other than that I do not know what the variables were. I will add grommets to my next batch of test samples.
Fair leads,

All the ones I've built so far are brummeled sans any lock stitching or cover.
So it sounds like, if I've assembled them well I can expect closer to 180%

I will see if I can get a few built to send off to Evans for when he begins his next round of pull tests. More data would be better than less.
