I just made a new set of Whoopies yesterday and since I didn't know the answer to this question myself I made them extra long before the bury and they came out to length after the bury. I am giving them away at the HH.

Predictions are risky, especially when it comes to the future.
Actually, if you go strictly by Samson's instructions, total bury in a stitched bury would be 63 times the diameter. Samson calls for 3 fids in a normal bury, 2 in a locked brummel. 1 fid equals 21 x rope diameter.
So for 1/8, total bury for a stitched eye would be 7.6 inches. 7/64 is 6.8 inches.
OK, so when they fail, I will know I should have made them a minimum of 7 inches buried. Thanks.

1 1/4 Fids or about 3"

Also, if you follow their instructions they show the fids are measured out before construction, so you worrying about a measurement that you aren't given in the instructions. I don't have the link for the instructions but its on the Samson sight. Implied and verified by Opie's tests, Samson has a safety margin built in so that the rope will fail before they're designed bury SO in reality, I wonder how many gram weenies have gone to find out just how much shaving off the safety margin they can do for our applications. Do we really need a constriction that will hold 1600 pounds? Maybe 800 is enough, how much rope do I save on each end for that?
I have seen my friend hang from a 6"ish straight bury on 7/64 and everything was completely fine. I think mine are 6" for the locked brummel and 14" or 12" for the straight.
I'm curious what the dynaglide calls for. I've been looking for it but no luck.
Again, according to Samson, the locked brummel requires 2 fids, which comes out to 4.5" in 7/64. There is some speculation that the brummel itself carries the majority of the load and you only need to bury enough tail to keep the brummel from pulling the braid apart. I saw a video once where someone just performed the brummel and load tested it. It held to 50% of the average strength of the line before the braid came apart. It didnt break, just unraveled.
