Procyon: Good point. I'll probably move it between the two Ka+.
Vandervecken/JoeBuckeye: That's all valid (I'd actually forgotten that Xa could count towards a system body survey). That said, one thing I want to avoid is optimizing everything, which to my mind is undesirable metagaming in a game such as this. Hence, a hefty reliance on the dice (actually the RANDBETWEEN function in Excel) to decide things. Yes, it's often less than optimal, but name me one real-life nation that runs everything in an optimal fashion. The races in this campaign will probably never do things in an optimal fashion, and to me that is a good thing.
