A new version of the Ger/BB/1905 design

I have a new version of the Ger/BB/1905 design that is based on a good set of specifications. The only thing that is abnormal is setting the machinery date to 1909 to obtain a higher power output for a given machinery weight. This is a ship that was intended to be 580ft x 90ft x 26.6ft with a displacement of 22,000 tons. The armement is 8-12in/45 BLR and 12-4in QF guns. The armor basis is 10 inches. This is the new Springsharp report:
