How does this game count up PvP wins?

[Altair]

Well firstly I'm very confused about this matter. My guild is a PvP guild, meaning it has a lot of people who PvP, and are great at it.

But, what’s a little weird is that on the guild rank thing, it shows that we only have 3 Team Battle wins, and no Mayhem wins which is completely absurd. I alone have more than 20 wins a day, so how can this be?

How exactly does this game calculate PvP wins, like 1 for each 10, or 20, I don't understand at all.

Thanks...
