Okay, this might be in the book, but hell if I can find my CRB - so I'll ask here. lets say that you have 4 players and they all have 24 duty each for a total 96 group duty. In the next game, they blow up a imperial convoy and everyone gets 10 duty each, meaning that the group had 136 duty.
So - duty level goes up at 100, what happens to the excess? Does that mean everyone is at 0 or 9?
