Im preparing to develop a PImpire across three characters and before I start to pour Isk into it, as any boding industrialist would do, Im creating my spreadsheets for it. Ive scanned down the planets that Ill be using, documented their individual results, and started to look at what would be most profitable. The issue Im having is I cant seem to find information stating how much is on a planet. Im not even sure what the scan showed me! Is it percent? If so, percent of what? Is it a linear amount? If so, is it the same for all planets and what is that amount?

Example of frustration;
I scan planet BOB, the results show a line ΒΌ of the way to full for raw material 'A' (R0 A). We'll say that all of R0 A is centered at the poles, Northern specifically, such that when I filter the scan, all of the result shows only at the pole. Further more, lets say that I have an extractor that just fits perfectly over the entire pole, harvesting at an rate of 100% of R0 A. The amount that I harvest, would it be the same if the exact same situation happened on a planet other than BOB? What is that amount?

Reason;
If I need X amount of RO A, how do I determine that a planet has enough? I understand that the rate of extraction varies, and that the practical way to adjust it is to set the cycle time to slower or faster. But if I wanted to make sure that a planet had enough resources on it that I could set the cycle time for a specific amount and still be able to harvest the needed amount, how would I do that? I havent been able to find any hard numbers for an equation.

Eve Uni put it this way,
If I have two planets, one that shows 1/10th of a full line on the scan result, and one that shows 1/5th (2/10ths), will the second planet yield twice as much raw material as the first?

There are no hard numbers... Yes it sucks

When you are scanning a planet for a specific material, as you move the slider looking for "hot spots", if you have white spots with the slider at 50% or more...
You can extract enough P0 for around four basic factories. The numbers are relative, not hard. The slider at 25% will provide material for about two factories, 75% six or more (normally limited by power grid).

Low sec planets extract at a higher rate than high sec. Null sec and wormholes better than low sec.

If you have not already, be sure to factor in the POCO taxes on the planets you plan to be using. Often in high sec (and sometimes border low sec systems) the taxes are so high, combined with poor extraction rates that there is no profit In it.

You say there aren't hard numbers, but it sounds like to me what you are describing is at least semi fixed number. Do you mean that there just aren't any hard numbers that are posted by CCP? If at 50% of the slider you can approximately run 4 factories, it seems like that correlates to a number.

I appreciate your input, you are saving me trial and error time.

When you say factories, do you just mean from P0 ( sorry, I thought it was called R0) to the first level of production? Example, adjusting the filter on the scan to 50%, finding a white spot of Aqueous Liquids, I can approximately run only 4 factories making water? How many extractors is that and on what cycle time?

Again, you're really saving me time and helping me plan to get it right at the get go.

Ok...
Kind of hard to answer, but I'm going to give it a shot. Had to log in and look at one of my planets so I could speak more accurately than from memory.

I'm Looking at a planet in a 0.2 (security status) system. The lower the number, generally the higher level of extraction you will have. This means that high sec normally sucks, low sec is better and Null sec and Wormholes are best...

I put down an extractor on a planet in this 0.2 system. I adjusted the "scan" or "survey slider" to the middle spot (50%).

Next I placed all 10 extractor heads, where they did the most good. In this case I did not have any white hot spots, they are all in the lightest red. To make them white need to turn down the slider about 5-8%...

Each extractor head is reporting numbers of about 135-150. I have never found out what that number means exactly, but it is a relative figure of output. Meaning that 150 on this head on this planet would be twice as much as 75 on another head on another planet.

Set for a three day cycle (that I use), this will give me a total extraction of 1,856,708 P0 units, or 25,788 per average hour (shows this on the bottom right of the extractor control window).

I know (because it tells you) that a basic factory will take in 3,000 P0 and convert it into 20 P1 every 30 min or put another way 6,000 P0 for 40 P1 every hour. SInce I know that I am extracting an average of 25,788 P0 an hour that means I can support four basic factories with this output (25,788 /6,000 = 4.29 rounded down to 4).

As you move up the production chain it is fixed. To make a P1 product you need 3,000 units of P0 per half hour to make 20 units of P1 (easier to say 6,000 per hour to make 40 units.

To make a P2 product you need 40 units of TWO DIFFERENT P1 products per hour. That means to feed the Advanced factory making your P2 you need two basic factories each making one of the needed P1. This will output 5 units per hour.

To make a P3 product you need an advanced factory that is being fed three different P2 materials. It requires 10 units per hour of each as an input. That means you need two factories of EACH of the three P2 materials feeding it. That is a total of 6 factories making P2 to feed the one P3 factory.

It scales the same way as you move to P4, Requiring two P3 factories of each of three different P3 items, fora a total of 6 P3 factories that will in turn be fed by 36 P2 factories, whom will be fed by 72 P1 factories.

I hope this answered your question somewhere in there. If I did not, ask again :)

Bear in mind that there are probably many players working that planet and depleting the existing resources. At some point new resources will spawn but not necessarily at a location convenient to your colony. I used to worry about balancing my harvest to keep the factories operating efficiently but it was a lot of effort and the results weren't worth it. Now, if I run short of something I'll simply buy it. If I'm consistently running out of the same thing, I'll adjust my colonies to make more of it.

the only "hard numbers" i can think of for PI are the extractor head qualities. when you click on the extractor unit and start scanning for mats, the next step is to create a head unit. when you do this, a number appears next to that head unit (in the GUI, not on the planet or anything). the bigger that number, the better. i do not know how this number is calculated, but i THINK it measures the overall VOLUME that particular head is picking up. and if you click show info on raw mats, itll tell you how voluminous a mat is then you just math it from there. if you wanna be a little more subjective, iv noticed that you really want your heads with a quality of about 150 or greater

hope this helps

thanks for the inputs,

Shelom Severasse, I think you're right, which means the extractor is our only accurate measuring device.

Do Little, unfortunately that changing variable does make figuring this out more difficult, but I think instant observations would still give us a clear result. Figuring out the re-spawn rate will take that variable into more consideration.

Scarlett LaBlanc, I appreciate your patience and information.

This question has rapidly grown from "what works" to "how does it work"

I did go out and drop 3 CCs on two different planets and at first glance I get the feeling that there is a fixed amount of P0 on every planet, and that the scan is literally showing you a number. So if every planet showed a full bar for the scan, then every planet would have the same amount of P0 available. This makes sense and seems obvious, but you know what happens when you assume. . .
One of the planets that showed approximately 0.5 of 1 (half a full bar) on the scan is able to feed 5-6 of my factories, while the same P0 on a different planet showing approximately 0.75 of 1 is feeding 8 factories.
So I have a hunch that the scan results of a planet is showing a percentage of a fixed amount. If that could be proven, then the next question is, do all P0 share the same total? Meaning, do all planets share the same amount of P0, but its modified by multiplying that fixed number with the percentage thats shown on the scan. The market would suggest this to be true, hence why Felsic Magma sells for so much higher then the other P0, because there is just physically less of it available. (This may be a bad example since it is exlusive to lava planets, but I used it because Ive never seen, in my limited observation, a result of higher than 0.35 for it)
So the formula that CCP used may have looked something like
Fixed Number*(percent shown on scan)=total amount of P0 to be dispersed on planet surface, which then of course goes through its own equation on where to be dispersed.
So HighSec has the same amount of "Fixed Number", but the multipliers are smaller, therefore giving a smaller amount of available P0. So it seems that Eve Uni had it correct, that the scan results is directly showing a number that is the same number for all scans showing the same amount., meaning half a full result of noble gas on one planet is the same amount as half a full result of heavy Metals on a different planet.

As a disclaimer, this is all based on theory and a tiny bit of observation.

I think this is obvious, but cant easily be proven since it is ignoring the fact that the available amount of P0 is spread out in varying amounts over the surface. I think that a hard number could be found though, with enough observations. I think to test, you would need planets that have the exact same scan results, and when you place the extractor, to place it where you get the same result with the same scan magnification.
To clarify, planets that have the exact same amount of P0 shown on the initial scan. Then to only place an extractor where white just starts to show, say at 0.7, and then repeat on other planets, placing an extractor where white just starts to show at magnification 0.7. Then of course comparing the results. If they are the same, then we have a fixed number, though we still wouldnt know what it was.
