False Brummel?

[arigger]

It's nice to finally find the master's site.
I'm hoping to get something straight about brummeling.
I am an entertainment rigger and, until recently, a lead on a crew that has been using 3/8" 12 strand technora [Tech-12] for guy-lines on some very tall towers.
The lines in question were spliced at one end by the company from which we purchased them. I noticed that they were brummeled in a quick and dirty manner that I have since seen called, alternatively: "S" type, stitched, zig-zag, McDonald... I call it 'false' since I've never seen any reliable documentation on the method.
It seems to me that the purpose of brummeling is to gain a high degree of security while retaining most of the efficiency of the termination. A "stitched" brummel will still allow the tail to be dragged out of the splice, and breaking the standing part over and over again can't be helping the efficiency any, can It?
I apologize if this horse is dead... I've searched around and no one seems to have an authoritative answer to this problem.
