The Ger/BB/1909 design in Springsharp 3.0b2 Beta

I just tried the Ger/BB/1909 in the lastest version of Springsharp, 3.0b2 Beta. The machinery, for the planned 60,000 SHP is lighter than I had expected and the protection is heavier. The speed as designed was 23 knots, but 60,000 SHP is good for 23.7 knots. The armament includes 9-12in/50 BLR and 8-6in QF guns. the armour basis is 14in, with 6in and 4in deck armour, although so far, it has to be lumped as 10 inches of deck armour. This is the Springsharp report:
