Would this be anything like "2 by 4's"? (The standard wood boards used in construction) The actual 2 inch by 4 inch board is not really 2 inches by 4 inches. It is before the rough wood is trimmed off. A "2x4" ends up really being about 1.25" by 3.5". Similar to "pre-cooked weight" I guess.

Thoughts?
