You made me go and review why I had intervened in the thread.
Yes, you are correct. Volume is an extremely imprecise measure for dry ingredients and it was because of that I commented as I did, as the discussion was as commercial baking/cooking revolved around large batches, measured by weight, while family cooking/baking revolves around measurements by volume.
But you get hard pressed to have that problem in recipes expressed in metric, even if we went and tried our best to make matters as complicated as possible and measured liquids by mass.
That was why a I replied as I did.
