Rosyth's crowded anchorage could encourage gunnery rotations

Adding the Kongos would put pressure on the battlecruiser force's crowded base at Rosyth. One proposed naming solution gives the Japanese ships the Seventh Battle Cruiser Squadron designation. Another gives them the Third Squadron title and renames the Invincibles as the Fourth Squadron. Sending that British formation to Scapa Flow for gunnery practice, then rotating other squadrons through, would also ease the crowding. Japanese insistence on regular gunnery drills could therefore encourage training changes across the combined force.
