Yup good luck.
If you want max profit. Don’t waste time with P1-P3 production. Just buy the mats and do P4. Value added is linear and there’s no cost savings to producing your own Pi unless you simply cannot get to Jita or other trade hubs to buy.
Does that make sense?
Basically. As long as you can get to the market, there is ZERO cost savings to producing your own materials.
But, to be honest the P4 market is pretty small. You can maybe run 3 of these planets continuously and last I checked profits were minimal I’m guessing because wars went into the dirt and nothing is expensive. (that was like 6 months ago).
So if you have to live off harvesting. Do the locust strategy on P1 to P3 products.
Basically pick planets that you can get all the inputs on the same planet…and just locust harvest everything you can until maxed out. Cram it into as many factories as possible. Rinse and repeat. Rinse and repeat.
Then as you build your P2 stockpile. Cram it all into factories and burn that stock pile down.
If needed…offload your P2 to the Customs then re-import it. Dependent upon taxes and efficiency of the planet (if you’re able to make a ton of Pi versus a little).
That way you’re basically avoiding having to travel and transport Pi (risk) until it’s maxed out on volume/value.
