Yes, volume can make up for waste, but outside of cave country, who does that volume?
I was just thinking between between say 25/25 (a Great Lakes mix someone mentioned) vs 21/35 from banked 10/70. Between eliminating the waste, and lower labor costs maybe even add in a touch of additional volume, would you be able to get the prices near parity?
Of course the assumes the shop isn't a one man operation, as most owners view their labor as being a sunk cost.
