I assume that my Ger/BB/1915-1916 design study is larger than anticipated

I have several pages devoted to the "Ger/BB/15-16" (Ger/BB/1915-1916) design study. Of course, on these pages, the critical information is lacking. Therefore, I made up the missing specifications. I have an inboard profile that seems to have 12-18in and 16-6in guns. The vessel is 915ft long. The citadel is 500 ft long. On the next page, there is a cross section with armor indicated. There actually are two decks: the upper being 6.5in and the lower, sitting on the belt, is 5in. The A/T bulkhead is 3.5in. The belt is 18in. There is a triple bottom, and the hold is divided into thirds, longitudinally. The draft is only 32ft. To make this work, I had to go with a large displacement and had to increase freeboard and draft. This is the resulting Springsharp report:
