Well, I'm no structural Engineer ( I did stay at a Holiday Inn Express last night) but I do find myself wondering about those darn holes. They may not be just "holes". He does mention a structured barrel and I'm thinking that the process of making those holes might also work harden the steel around the throat area, perhaps interrupting or channeling shock wave propagation.....or something like that. Anyone else have a competing idea?

Maybe it's just marketing double talk, like muffler bearings going bad and the flummer-agitator creating carbon on the valves. Or maybe he actually IS the little crack-pot in the basement we sometimes read about working furiously at night on the lunatic fringe of advanced science.
