Damage counting on the naval event

There has been instances where the damage counting for the event gave me less damage for the proggresion. Before playing my last game I had 8200 damage dealt, and after playing a top tier match with only the SMS Bayern (dealing 10800 damage) I’m now sitting at 16363 damage. Is there a reason for this?

Keep in mind that tier V-VI damage is multiplied by 1.2 times

It’s not damage, it’s score.

Lol that explains it
