After a recent Pirate War, I took time to look at my stats. I would've thought that Wins plus Losses would equal Attacks ? Nope. I only saw one fellow Pirate where this was true. I'll have to ask them what they're doing different.
I believe this is a function of using the stamina slider. 1 Stamina = 1 attack and either 1 win/loss 2 Stamina = 2 attacks and either 1 win/loss 3 Stamina = 3 attacks and either 1 win/loss To be honest with you I am not sure why it was built to tally like this but that is likely what is happening from what you describe above.
