Not sure how to test it. If you bend the loop just right you can get a hold of the tag end where to turns from the loop back into the standing end and you can start to pull it back out but you kind of have to intentionally try, I don't think it will work out on its own. Tension on the loop itself is directed right back into the standing end with little or no obvious tension transferred to the bury. It all catches on the intersection.
Figuring out the measurements is a bit tricky. The loop ends up compressed and the 7/64's seems to compress at about a 4:1 ratio plus you have another loop's worth inside the compressed visible loop. So to measure I'd figure out your final desired loop size and wrap the loop 4 more times plus the desired bury length down the standing end.
Really though I think the only advantage here is the looks if you happen to like it. Who knows, maybe its crazy strong too.
