The "Tiger" version of the more heavily protected battlecruisers

The natural thing is to have a 1911 British battlecruiser that is better protected. The design is Tiger-like, except for the soft ends. For better or worse, I am using reduced dimensions, as that increases the "composite strength" in Springsharp. I thought that this design needed to be 28 knots, at least, so that ballooned the displacement by 1,000 tons. This is the Springsharp report:
