I have had 3+ accounts (nearly max skills) running PI operations across several regions of space and sec statuses since it was introduced over two years ago and my long-term observations are that, nearly 100% of the time, the true rate of return is always less than the game-generated estimate when setting up my extractors for a new cycle.

From a practical standpoint. it is necessary to always shoot high and go for a shorter extraction cycle or additional extractors that yield more P0 materials than are required for P1 processing over a given period of time.


The duration of the program does not give a drastic increase in p0 production. If you start a 24h, 48h, 4 day or 8 day program. The amount of resources extracted after 24h will be almost the same. The small deviation is almost not noticeable in the long run.

I still disagree that the system in eve is massively inaccurate or does not work. It works as it was programmed. It however, does not take into account other people doing PI in the same spot.

It gives you the estimate of how much it will extract in the program length but does not take into account how fast the resources are being extracted from the place you are placing the extractor heads (due to other players). If the rate of extraction is higher than the rate of replenishment, the total yield will be less than what the initial program estimated.

That however most often is marginal compared to inaccurately placed extractor heads since you have no Planetology skills and are trying to extract water from a desert, instead of the sea that is 200km away. It only becomes noticeable if you have multiple toons strip mining the same spot.
My experience with extraction rates differs from yours where changing a cycle's duration has a dramatic impact on the P0 extraction rate. In my case that experience is on deep null-sec planets with no other command centers / extractors on-planet. The only forces at work are CCP's PI feature parameters, my characters' skills and the placement of extractors.

I am in agreement that PI is working as coded. Whether that means that it is working as designed is a completely different thing. It is up to CCP to confirm that point.

It is rare to see a developer / coder comment on PI mechanics from what I have seen on these forums. The last developer blog was nearly a year ago, too. With the upcoming DUST integration, it sure would be nice to have CCP touch base with customers on this feature.

How so? Could you elaborate a bit more on these results?


Currently, i am running my planets inside a wh and i tested this in high sec, low sec and wh space. I haven't tried it it out in null sec however.

In high sec, it is a pain to get an accurate quote since everyone else and their grandmother is using the planet to extract the resources and the actual resources present dips so low that the quote can be wrong upto 20% even. So it is much better to use 12-24h cycles, since the amount of resources changes quite fast.

In low sec, most planets were with a good enough quote and the change in extracted resources was not really visible. The 24h / 4 day cycles came out at near 95-98% at the 24h mark.

In wh space, there is almost 0 difference visible between using a 24h, 4 day or a 14 day cycle. Even with 3-5 people using the same planet.


The only times it did change a lot was when the hot spot was tiny and the amount of extractor heads no longer fitted inside there. If space allows, running a 4day or 24h cycle doesn't matter under optimal conditions.

New discovery! The inbound route of p0 from the extractor to the starport gives a THRID number! How the hell am I supposed to know which one is real???

the volume shown on the link is per load/cycle. If you are running 15 minute cycles this should be roughly 1/4 of your hourly extraction rate. If you run 30 minute cycles it should be about half. with 2 hour cycles it would be double.

Also the more your extraction graph fluctuates the less accurate this number is as I believe it shows the volume for the current cycle not an average like your extraction rate.

Also as others have said. you have no idea how many other characters are using the same planet. the show other players networks has never worked. On a busy high sec planet your survey will not mean much as it is based on the rate you would get if your extractor was the only one on the node. Even in high sec I use back water planets where there is far less activity.

I do pi in deep nullsec. The chances of anyone else using these planets is pretty low.

Couple of points to consider.

1. Other people farming your node is huge, and hard to detect. Your pre-install value doesn't take other extractors into account, obviously the one you see after submitting does. If you right-click and Show Other, you only see other Command Centers. Then you can click on one and see the facilities associated with it... that could be anywhere else on the planet. And you can't see their extractor heads to boot, although their extractor positions are relevant. So it's rather difficult to avoid in advance. The best way to avoid this is leave highsec, not only do you get better nodes but far less competition.

2. Planetology gives you more accurate surveys. Advanced planetology lets you see hotspots that unskilled people can't. If you are taking PI at all seriously you should train adv. to at least 3. On the flip side, I have never seen what people are talking about re: remote Sensing. If you don't have a CC on a planet you can only survey within RS range. Once you do have one though, in my experience your range from the planet is meaningless. I've seen no difference in scanning error when updating extractors from literally the opposite side of the entire map.

3. On many occasions I've installed programs and had the final total go *up* compared to the pre-install estimate (sorry, no screenshots ATM). I think this is related to another phenomenon that many people aren't aware of. The hotspots spawn in a series of waves. Then the materials spread outwards, gradually dissipating as they go.. That's how the ring of lower concentration gets generated around the actual hotspot.

Where this gets funky is that the server isn't trying to update the concentrations continuously. It's periodically moving material outwards, and then checking if an extractor happens to be at the point in its cycle where it can "see" the material. Because the process happens in fairly spaced out intervals, in order to keep server load sane, there's a big random factor as to how many of these waves a given head will actually catch. Often, having a head right on top of the hotspot means it catches fewer waves, and thus has less output than if you slid it away a little. So you can get higher totals by making a ring around the hotspot instead of packing your heads in tight. Having the post-install total go up could mean that my estimate had me missing more waves than the actual ended up being.

4. The number on the link showing the % used is based on how large the program's peaks are, with some kind of averaging thrown in. As far as I can tell it's not directly linked to your overall output. One thing that again many people don't realize is that the "unrouted" number only applies to the peaks in your program. If your extractor says 62,500 routed, 6250 being lost, that 10% only gets lost from the highest parts of the program. The rest of the time you're getting everything extracted. So don't be afraid to leave a little unrouted, it basically won't matter.

5. To whoever is having trouble maintaining balance with P2 inputs: You have a spaceport, don't you? And perhaps you should build a silo as well. A bit of error in your program doesn't matter if you can store several hundred K in spare raws all the time. And if it gets really wack, export a couple hundred ka nd use them on another planet. Or build one more P1 fac. Sheesh.

the reason people are harping on how the heat map changes with the advanced planetology skill is because when they give you the estimate on the extraction screen is based on what your planetology skill reveals the heat map to be IE what your pod pilot thinks it is.

When you start the program, you get what it actually is.

The reason people are telling you to train planetology is because that makes what your pilot thinks the planet looks like more accurate and thus give you a more accurate estimate.

that's not completely accurate. On the previous page, i posted the screenshots to the test i ran with skilling up planetology on an alt and the yields increased on the same program. The amount of minerals extracted was not what it proposed also iirc. It was capable of running 2 p2 factories with a 4 day cycle but the program said it would run out of p0 in 12h.

However, with higher planetology skills the 'dip' after hitting submit has gone down so much that i no longer notice it. So could be something on the lines of real materials extracted but not taking into account hot spots?

Saw an underestimate for the first time yesterday after doing PI for 6 months. I'm leaning toward the position that planetology reduces the variance, but it never goes away completely because it doesn't calculate depletion or regrowth of resources.

Yes even with perfect skills, and sitting in orbit around the planet, you are still not at 100% accuracy. probably 90-95%

But the same scan with a character without palaeontology trained will only have maybe 5-10% accuracy.
