Alright.... E1 is becoming a real problem, since people are not supplying it correctly, so I'm going to outline the process here:
1. Supply the NPs first!
With the exception of Egroeg's NP, they all buy E-Matter at 1030, so you can buy E-Matter from the Black Market and supply them at a bit of profit. They also all sell their energy at a maximum of 90, so you can make a good profit by carrying the energy back to Ericon 1. Dont forget to get rid of the Neb gas and take the NPs food and water, too...
2. Supply the Farms around TrC and ACS... They should be the first place you get food for the SBs.
3. FWE - once the farms and NPs are empty, start FWE runs. Since they're longer, you will be using the most APs in this section and therefore dont want to do as many of them (hence doing them last).
Once the SBs and planet are supplied, STOP! If you take more food and water from the planet, the prices will increase and will not drop as low after the next planet tick.
3 hours later, repeat... Logging on every 3 hours will enable you to make the maximum profit. With 150 cargo space, you should be able to make almost 400k a day doing supply this way.
If supply is not done with way, food prices on Ericon rise, and therefore you will only make a fraction of the profit.
