Expected Return:
2.0 to 2.5 million isk a day per colony.
Expected difficulty of maintenance:
Minimal - less than 15 minutes a day to operate, all the time investment comes from haulage.
Skill required:
Command Center Upgrade lvl IV.
Market Strategies:
Sell to buyers - this takes advantage of sales tax. The spread between long-sales-prices and brokerage fees is often underwater unless you have amazing brokerage rates.
Definitions:
P0 (Raw resource extracted from Extractors)
P1 (Made in a BIF from P0)
P2 (Made in an AIF from 2 types of P1)
BIF (P0->P1 Factory)
AIF (P1->P2 Factory)
LP (Launch Pad)
Ratios:
1BIF consumes 3,000 P0 to make 20 P1 every 30 minutes (40 an hour)
1AIF consumes 2 types of 40 P1 to make 5 P2 every hour.
So - it takes 2 BIFs to fuel 1 AIF.
And it takes 1,500 P0 every Extractor Head cycle to fuel 1 AIF.
The setup:
The best Set-up uses a split base to get more coverage over the entire planet. This is a strange split, but I’ll explain. It costs nothing more to operate, but it gives you the ability to reach more resources since resources move around, preventing you from having to move Extractor Heads around as much
Base 1 - Colony 1: Just a Silo
Base 2 - Colony 1: Launch Pad with 4 BIFs fueling 2 AIFs
Visual representation of why 2 bases the way I showed:
-
Black represents base and extent of links or of maximum range of Extractor Heads from Extractor.
-
Yellow represents the links between base and Extractor Head.
-
Red is the Extractor itself.
-
Blue is the temporary link between the two bases when needing to Expedite Transfer from Silo to LP
-
The method is when you shut-down your Extractor programs for moving the Extractor Heads to better resources, you remove all your Extractor Heads, you build a link between Silo and Launch Pad. Doesn’t matter how far, you can always upgrade it. And you Expedite Transfer the resources you need to your Launch Pad where your factories will be.
-
This method is very easy, is a lot less point and click while giving you better access to the whole planet.
-
This method also takes advantage of the fact that on most planets, you won’t be able to extract enough resources for more than 2 AIFs to continuously operate.
-
If you consider how much you can operate at CC upgrades level 4, you will find that you are probably NOT going to harvest the 18,000 P0s per hour needed to continuously run 3AIFs.
And to use 3 or more AIFs you will have to sacrifice the dual Extractor Head, which needs 36,000 P0s an hour (9,000+ P0s per cycle continously) to make-up for switching the Extractor Programs between the two required P0s.
This is not unusual, it’s just what it takes to go from 2AIFs running off 2 Extractor Heads (more common in High sec and Low sec).
But if you can extract more than 9,000 P0 per cycle, then you can run one Extractor Head, switching between both P0 programs required, and continuously run 3 AIFs.
