How do I tell what a maximum pop for a planet will be?  At first I thought it was because I don't have enough farms, but then I noticed that planets with lower ratings seem to have a population cap.  Is there a way to figure out about what the pop cap is gonna be?  I can't stand taking planets only to find I can only get about 2 billion people there, and they can be taken out easily by a lone troop transport.  I'd rather just pass those planets by!  Thanks.
