The Ger/BB/1916 Large is amazing to me

I just ran the Ger/BB/1916 Large design study through Springsharp, and was very pleased and amazed at how well it did. I must confess that I don't believe the result, but I had happy to see it. This was for a ship 1085ft x 140ft x 38ft, with 9-19.75in BLR and 24-5in QF guns. The armor basis is 19in. The speed is 31 knots. Great length makes this easily attainable, even with a 1916 machinery plant. This is the Springsharp report:
