Basic physics dictates that every action has a reaction.
Greater surface area DOES cool faster, but the barrel must also then heat up faster according to physics.
What we do know is that metals of varying thickness heat and cool at different rates so the barrel heats unevenly through out its diameter. How this can be any sort of accuracy enhancement eludes me.
What we are seeing now (under the borescope) as more and more fluted barrels come in for replacement is that the firecracking in the bore is much worse where the material has been removed to create the flutes. This would lead to to believe that accurate barrel life may be diminished.
Frankly the only benefit I see to fluting is that it makes the person doing the fluting richer.
