Willis Lee and a better-trained battlecruiser force at Jutland

How might Jutland change if Willis Lee commanded the British battlecruiser force?

The force would probably exchange information more effectively and enter battle with substantially better gunnery training.

Jellicoe would likely welcome an unusually capable American subordinate. Admiral Lee would demand better communications with the Grand Fleet and would not tolerate the battlecruisers' weak gunnery preparation. Regular squadron rotations to Scapa Flow could expose the force to Grand Fleet practice while preserving a concentrated striking group farther south. Lee would also press the defective-shell-fuze issue, giving Jellicoe a forceful technical case for correction before Jutland. The payoff comes from institutional preparation before battle rather than a miraculous tactical intervention after firing begins.
