Quick Duty Question

By KungFuFerret, in Star Wars: Age of Rebellion RPG

So I'm listening to the O66 podcast about Duty, and the way they're talking about it, implies that Duty works in a way I wasn't aware of. I don't have the AOR book, and when I read through it at my friends, I usually just skim for some specific subject. So I apparently missed this, but, it seems Duty works like this:

You have the various members of the party, each with their own Duty type, and score, but once the cumulative score hits 100, they have reached a new Contribution rank.

Is that correct? Because I thought it worked once you got any single Duty type to 100, but it seems like it's the cumulative.

Thus meaning, a Space Superiority of 50 + Tech Procurement of 30 + Counter Intelligence of 20 = 100 = New Contribution Rank/Reward.

Is that correct?

Yes. It's the group total.

We don't actually use Duty, but this is how it works in RAW.

K, just wanted to clarify, thanks.
