The alternative starts by building four Dreadnoughts instead of a single ship. The later construction comparison counts ten British battlecruisers, including the Invincibles and Indefatigables, then Lion, Princess Royal, Queen Mary and Tiger. In the scenario, each of those slots could take a battleship order. Even if Germany likewise switched its battlecruiser orders to battleships, the change would not add the same number of hulls to both fleets.
