That seems really good. I fear I am misunderstanding something.

Am I wrong?

No, you're right. Provided you hit with each attack, 1 extra damage per volley.

Cool. That will be fun.

Which also means you can spread the love around. It doesn't have to be the same recipient of the extra damage point. If the opponent is flying in tight formation, you could damage up to 3 ships here.
