Hey y'all

So correct me if I am wrong, this is just a theory. If I were to breed 100% piebald het cinnamon to a 100% piebald black pastel would the babies come out as possible piebalds, super black (solid black), lower percentage het normals, cinnamon, and black pastels? Also what are my chances of getting a piebald and what kind would it be? What are my chances of a super black , I heard 1/4 percent? I've given this a lot of thought haha. Fill me in guys

Thanks!
