The very large German battleship design works well in Springsharp

My very large German battleship design, which I am calling Ger/BB/1921 large, that I drew back in 1971, works quite well in Springsharp. I was able to upgrade the armor and range, as there was spare hull strength. The armament is 9-50cm (slightly more than 19.75in) and 16-6in QF guns. I had planned to have 19.75in guns, but 50cm seems reasonable. The armor basis is 19in. The ship was to be 105,000 tons with a speed of 31 knots. That works along with machinery of the same date as the ship design (1921):
