Thanks … those make sense now myself I tend to use a much less maximized approach & go for flexibility as I’m still working out what (I think) works profit wise.
So I tend to throw a line of storage silos down 1st then add the factories in down the side of that line so I can see what mats I have at each stage, production progresses down the line drawing from the previous silo & delivering to the next.
I pull what I want to export to the launch pad with an expedite when it’s ready & send it up.
Currently all my PI alts are alpha so I’m having to stockpile on-planet until I can get around to plexing those accounts again … which means I’m concentrating down to the highest level mats I can on each planet just at the moment as it all takes up less room that way.
Other projects have my priority attention (& available ISK / PLEX) right now though or I’d PLEX up & give your designs a go, looks good
