Okay so this question seems pretty basic, but I haven't been able to make it work in practice, so I was hoping someone here could shed some light on the actual math around it. How much P0 per hour should I expect a processor to be consuming? Basic logic would dictate that every processor would go through 6,000 units of P0 in an hour (2 x 30minute cycles consuming 3,000 units each). So I usually just take my average hourly P0 output, divide it by 6,000, and build that many processors to deal with it. So for example, if my extractor's average P0 hourly output is 48,000, then I would build 8 processors (48,000 / 6,000 = 8). Usually I will fill in any extra powergrid with extra processors simply to deal with future extraction cycles that output more than the system was originally designed for.

I will sometimes come back to check on my PI only to find that none of my processors are processing anything and there isn't any P0 in the system at all. For example: one of my current planets is currently extracting at an hourly average rate of 41,927. This would seem to mean that 7 processors would be ideal for this setup (41,927 / 6,000 = 6.98). I filled in the system such that there are 10 processors being used to account for any future large cycles. Despite being only 3 processors over the number that would seem optimal, there is currently a total of 2,877 P0 in my entire system (sitting in the holding area of one of my processors). I would think that even with 3 extra processors, the system should be putting out enough to at least be producing in a few of the processors? Or maybe I am just being dumb and not looking at the numbers the right way. Are 3 extra processors really all it takes to outproduce that P0 output?

I realize that this is a lot to read through, but I am having a bit of a difficulty getting my head around these numbers and would greatly appreciate any help. Thanks.

the per hour is not really relevent as there is a large amount initially and sometimes a few bumps of good yield thru the cycle you set, near the end tho will be lots of low yield all together

so you over build because you are considering the per hour and not the cycle total

i.e.

you say 48k/hr, assuming 24hr cycle it will make 48,000*24=1,152,000

you set up for 8 factory, but toward last half of the extraction you will only be getting ~20-25k/hr

so with 8 you will have excess mfg capacity, as yield isnt constant

as long as you arent ending up with lots of p0 every day that is still needing to be process you are doing fine.

re-open extractor heads after you install and confirm build and you can see the graph show the dropoff i am talking about.



another thing is that the factory will take the 3000 units for the next batch into itself as soon as the current batch starts not on completion. so there is a buffer of material that you may or may not realize is occuring

We are our own worst enemy.

Thanks for your response! That does make sense. I had seen this drop-off occurring and just figured that the large amount that extracted in the beginning would pile up and end up carrying over farther towards the end when the extraction rate was less. But I guess it does make sense that any extra extractors would get through any front-loaded pile-up quicker than I was anticipating.

The 3,000 buffer held in each processor was another thing I was considering. I guess for the time being I will go ahead and figure out just how many P4 products I want to be making per hour and see just how many P1 processors that will require. I guess its easier to engineer P1 production when you have some idea of what you need to be making for down the line.

If you do not have your planetology skills trained to a high level, the estimates you get for you extraction amounts are very imprecise.
just occures to me: make sure the link between ECU and the storage is's using isn't at 100% capacity.
I think with 48000 per hour you'll need a upgraded link.

Yeah ive got Planetology 4/Advanced Planetology 4, so I should hope it isn't an issue with my skills. And the setup won't even let you route your P0s to your storage if the link is full, it forces you to upgrade the link first.
