Is there an optimal fleet size for auto trading/mining?

[Doc_Orange]

Hi. Actually I'm using 12 miners (M) and 13 freighters (M) for automated mining/trading. I think to expand this fleet as in investment for later money. Is this meaningful or are the not enough wares or loot for a higher amount of ships. When I look to the stations the offers and demands are limited.

In the current iteration there are no major draws on resources. So once it hits a certain point it stalls out your probably reaching the limit.

Things currently not working
Wars
Raids
Station Building (at least in a meaningful way)
Station Destruction (cause no real wars)
