The alternate battle does not give the Royal Navy the later Greenboy armour-piercing shell before Jutland. Officers already understood that existing shells had problems, and Jellicoe had pressed for investigation while serving as Third Sea Lord. The obstacle was political and industrial willingness to force manufacturers to change during wartime. A decisive victory could let defenders argue that the ammunition was good enough because the fleet had won. Reform remains more likely than not, but success can conceal technical defects and weaken the case for procurement change.

Victory could delay British shell reform
A clearer victory would create the paradox that Britain might lose the political pressure needed to replace its unreliable armour-piercing shells.
