That is just not true.

I've done destructive testing with my own splices and it's what I've found. I can even tell you where the splice will snap. it doesn't snap right at the bury but away from the bury by about 6cm. I encourage you to do your own testing.
I am not sure what you have tested, but my own tests on sk99 dyneema say something different. With a blunt splice the a 1.1mm dyneema line with a 10cm bury broke between 380kg and 410kg. That is pretty much at almost 140% breaking strain. With the taper the way I do it, it broke between 410kg and 430kg, which is about 150%. Also statistics and also most literature on this does not support your statement of 50% .
Thats your problem right there, thats how do you say not possible To be less rude your testing numbers are wrong or the manufactures numbers are wrong, I would say both are wrong with a leaning to the manufacturer.
I did do a lot of testing on this stuff and edt was in the thread discussing it with me. Now I am not entirely sure what you two are talking exactly about and this is from memory ( not the best). Tapers have little to no effect on strength but not using one would seem to cause long team wear on the line. The brummel itself is about 50% strength and if the tail slips and the brummel gets tight it will weaken down somewhere towards 50%. The strength in a brummel is from the tail. Another good reason for tapers especially with foils is they make the line smooth and less likely to knot and the tail end is less likely to pop out.
