Again, the "rounds" do not indicate execution time, thus execution time is not a good determination of how "secure" a hashing function is. There is inherent mathematical reasons why the combinations of the functions should be strong. It's why s-boxes are accepted practice. Agreed, cryptography is a tricky field. All the more reason to stick to systems that are carefully reviewed by experts smarter them myself and you.
