How important is throat diameter for precision

You're on the right track! Increase laminar flow, reduce turbulent flow! Simple air and fluid flow dynamics. Remember, there is friction at the surfaces even with gas motion. Especially with hot gases! Always remember that Friction adds more Heat! Friction can also cause turbulent flow! Yes, heavy bbls absorb more heat than thin. But, at a price! The thicker material takes longer to transport that heat and dump it into it's surroundings (Air)! It is based on thermo conductivity (one of several Physical Properties) of the steel alloy of the bbl.

Aim small, hit BIG!!!!!

I haven't seen any down sides yet but it's way early and it's way, way too early to draw any conclusions about bbl life yet. I can see potential for a big jump in bbl life but I could be wrong and time will tell.

I'll add that I do think those small turbulence points add greatly to where carbon build up as well as where heat concentrates most...fwiw
