My only confusion as to network scoring is how to score branches. If, when scoring my longest chain of connected cities, I had a chain of 4 connected cities and a "branch" of 2 chains. Will my personal offices in both of these "branched" cities score, or will only the first city in that "branch" score? .
Network, not chain. Connected group, not line. And offices not cities, and pick the biggest possitive all-offices-in-network network, don't try to count the cities first and let the offices fall where they may.
