How do I estimate diagonal lumber sheathing amounts?

slugboy6000 | Posted in Green Building Techniques on

After drawing some sketches, it appears that I should add 15% to the square footage of my walls to allow for waste created by diagonal end cuts, and unusable short pieces.
Does this sound ok?

I’m sure there’s some rule of thumb published in an old carpentry book out there…but I can’t find anything.
