The basis is the harmonics and a few small other things. It is well known that a straight barrel tend to whip less. What they have done to what in reality is a straight profile barrel is to block the path of the barrel’s harmonics. They flute and drill based on computer simulations of the barrel’s harmonics. They are also changing the cooling thermodynamics reaction of the barrel. As I have said a few times I understand the Engineering of the idea. What I am unconvinced about ( due to the incomplete test protocols) is to what extent they are actually making meaningful change.
If is interesting that the new Noveske DDF series of barrels is claiming the same benefits. They have used a different easier path , no holes but deep rounded flutes, to gain the same results. This in principle should gain some of the desired outcomes with the ability to built at rate.
I am still interested, not enough to buy one, but interested nonetheless. I am waiting for more concrete studies and victory plaque evidence. But as always I love true innovation.
