Earlier contact gives Jellicoe time to build a trap

The larger operational effect of reliable reporting is that Jellicoe keeps the Grand Fleet moving south at about twenty knots. Depending on when the first message arrives, contact with the High Seas Fleet might occur an hour or more before the historical deployment. A battle farther south would be closer to German-controlled waters and minefields, but it would also begin with much more daylight remaining and less night cover for Scheer's escape. Historically Jellicoe organized his deployment from Goodenough's late report in roughly forty-five minutes; repeated updates could give him much longer to form the battle line and place destroyers and torpedo attacks. The British guns and defective shells remain unchanged, so the advantage comes from time, position, and preparation rather than a technical miracle. The resulting interception is a deliberately arranged trap instead of an improvised response to sparse information.
