Reading secondary-gun results in a simulation

What do the displayed results show about the ship's secondary guns?

This report credited larger guns, but four-inch batteries have been effective in other engagements and cannot be judged from one display alone.

The game's damage display credits the six- and 15-inch weapons rather than the four-inch battery in this action. Smaller weapons remain relevant because four-inch guns have done substantial damage in other simulated engagements. Their contribution also depends on the range at which the action develops and the targets they are meant to engage. One report cannot measure the full value of a secondary battery.
