One question I don't think was answered, and perhaps there isn't an easy answer, is, aside from changes in POI, can a brake affect accuracy? I assume not, but I don't know what happens with pressure waves when a bullet is exiting at 3,500 fps through something with a bunch of staggered holes. It is probably nothing, but it someone experienced reduced accuracy with a brake, I would be eager to just put it in a drawer or tub somewhere in my garage.
If anything, a brake potentially increases accuracy for two reasons. First, it reduces the recoil that can negatively affect accuracy if not well controlled, and second it results in recoil that is straight back, avoiding muzzle jump that can have a negative impact on accuracy.
