Better scouting could bring Jutland on sooner

Which historical fleet action would be chosen for a counterfactual refight, and what would change?

Jutland: retain Jellicoe, put Horace Hood in Beatty's role, and give the Grand Fleet faster, more accurate scouting reports.

Jutland is the chosen historical fleet action, with the Norwegian campaign as the other strong candidate. John Jellicoe remains in command of the Grand Fleet, while Horace Hood replaces David Beatty. The more important change is a steadier flow of accurate position reports from the scouting forces. Better information would keep the Grand Fleet moving at speed instead of slowing while Jellicoe resolved uncertainty. That could bring the main fleets into contact earlier in the day and leave more daylight for the British battle line to exploit its deployment.
