Thanks CMDR;
By predictable re expansion destination, do you mean they will arrive at the nearest system unless they are already there or its filled. If a faction already controls a certain type of economy, I was hoping that the bgs would pass on going into another one even if its the closest available system.
Its a basic formula - I think its posten on the OP, but to state:
The closest system from the Point of expansion with room (having 6 or less factions) within 20 Ly.
It is assumed the Investment state expands the range to 40ly, but it "might" also allow for the system to be more full as I have seen systems with 8+ factions in them. But those may be holdovers from prior to the expansion mechanic change sometime last year.
