If the Jutland battlecruisers had survived

What might change if the British battlecruisers destroyed at Jutland had not exploded?

More surviving hulls would provide better evidence about damage and protection, potentially improving later capital-ship designs such as the Admiral class.

The consequences depend on whether the British battlecruisers return largely intact or as badly damaged as Seydlitz. Badly damaged survivors would need repair and could then be assigned to more distant stations. Their survival would also allow detailed examination of the damage and possible improvements to protection. More surviving ships would provide more evidence for the next generation, affecting the Admiral class and the question of whether Hood was built.
