How Beatty's first contact report could move Jutland

What if Beatty sent his first contact report promptly during Jutland?

Jellicoe could arrive earlier and maintain speed, creating more daylight engagements and substantially heavier German losses.

An immediate and accurate contact report would let Jellicoe maintain speed and shift the location and timing of the main engagement. More daylight could permit three fleet contacts rather than two before nightfall. German ships already damaged in the earlier fighting would then face a much harder withdrawal. The watch point shows how signals discipline can change a battle without changing a single ship.
