As I understand it from the manual:
A traderoute, once set up, has a ship travel back and forth along its length. The farther the ship is from your world, the more money it's making.
An economic starbase with "trade" modules increases the amount of money from a route while the ship is within the influence area of the starbase? And while the ship isn't, it does nothing?
Doesn't this mean that you're better off making short trade routes that can fit entirely into the influence of such a starbase?
If you have a long route, doesn't this mean that you should place your starbase on their end of it, rather than on your end?
I'm confused as to what the manual implies...
