Compare that with a straight splice where you can easily adjust it and get to better than 5mm accuracy every time.
I created a small spreadsheet of each diameter line I use that I am looking for accuracy on and how much the line shrinks due to the brummel bury, ie. the 7/64"(2.78mm) dyneema(pigtails), the 1/8"(3.18mm)dyneema(beefier pigtails) and then the flying lines I use. When you handle a straight bury, even after pulling it tight I've seen it work loose 1mm which is greater than the deviation I have with my brummels.
Also, when making center lines and steering lines, you can have poor accuracy and make that up with your pigtail accuracy. For instance, my center line pigtails larks head to the small diameter center flying lines then I just knot them off on the other end to exactly where they need to be. For the pigtails on the steering lines, you have to be crazy accurate with your pen marks and exactly where you work your magic....after enough practice it is very accurate on length. BUT....remember your last course of action to dial in the steering line lengths is adjusting your knots coming out of your bar ends....so in theory if you build your bar correctly, you can fine tune any goofy mishap you may make with the brummel losing accuracy.
I just had to rebuild my switchblade bridle from pulley wear and used the 1/8" (3.18) dyneema and dialed in my brummels carefully and the deviation was almost unnoticeable.
Also, one trick I use that may or may not be helpful is once I have the brummel lock done I don't pull the living shit out of it before the tail bury, I don't loosen it per say, but I try to make the tail bury carry the load, vs having a crazy tight brummel lock before burying the tail. Maybe meaningless, but I am looking for the tail to carry the load, vs a weak tail bury causing the lock to carry the load. I'm also using 60x bury lengths, I'm working on a bar now with a wichard quick release and may need to use a much smaller bury for a certain area that I'm concerned about, but everyone here hasn't seemed to have problems with those small burys on the thicker dyneema lines.
