How is the Scrupulous Trait supposed to work?

[grävling]

I have a crew with the Scrupulous trait.
From the wiki "A thorough and focused approach helps bring missions in successfully, gains +5% on all Mission payments (3 max) Grav +1"

I don't know what the (3 max) means. Every single mission I run, when I get paid, I have this talent announcing itself and my increased payment. It's wonderful, if that is what is actually happening (and not it singing out even when it did nothing), and vastly better than a +1 trait.

Suspect it is a bug I should enjoy while I can ...

Your max is 15% from three different crew with that trait. I'd agree that is a +2 trait though.

What is "Grav +1"?

from the wiki table, the trait is in the grouping 'Grav' and has a meta-score of +1. I do not know why it has either.
