The "All-or-Nothing" version of the fast battleship

I thought it would be interesting to see what an "all-or-nothing" approach to protecting the fast battleship would be like. Admittedly, I felt obligated to thicken the armor that was used, so the displacement increased marginally. Instead of a 12in armor basis, the armor basis is now 13in, with a slightly thicker deck. The thicker deck certainly increases the protection over what it was before. I also took the step of raising the secondary armament to the upper deck and removing protection, American style. I'm not so sure that I understand why this is a good idea, but I did it anyway, as it seems to be "part of the package". This is the new Springsharp report:
