PI - relationship between amount sent over link and amount harvested

I am curious about the relationship between the amount being sent over the link and the actual amount harvested.

If you look at the ECU panel (not the survey panel with the graph) you can see the amount routed over the links in one of two locations. Either the products drop down, or the routes drop down will show the same number which appears to be the number of units being sent out of the ECU over the link.

Does anyone know how this number correlates to any of the values shown on the ECU Survey Panel?

The only near correlation I can find is that the amount sent over the link multiplied by a number that ranges between 22.3 and 22.9 equals the total units (as shown on the survey panel bottom right corner) ( I am using 4 day/96 cycles).

It would be very nice to know when optimizing a planet, that the max harvest can not exceed a set number for the link, but right now for my example, that number would range from 557,500 to 572,500 units for a basic link during a 96 cycle program.

Thank you in advance if you can shine any light on this relationship.

The per hour number on the ECU is the real number. You should be using that in your calculations.

But I don't get what the amount being sent over the link is all about... Seems like it doesn't correlate to anything. As you increase the duration of your harvesters, hence decreasing production per hour, that number actually goes up, which seems like it is backwards.

The per hour number on the ECU (assume your talking on the survey panel) is the same number as the total, just divided by the number cycles. So both of these numbers are good I think. The issue I am still looking for clarification on is how these relate to the amount sent over the link as these don't correlate well. (Seems like a fudge number between 22.3 and 22.9)

Still hoping someone has the answer.


Thanks

It goes up because the longer the overall cycle, the less often it sends over the link...so on say, a 4 day cycle, it only sends stuff down the link ONCE every two hours....so the longer your cycles, the more you have to upgrade your links

Wow so no one knows the relationship between the amount shown as being harvested in the survey panel? (regardless of whether you look at total or per hour) and the number in the ECU panel under route or products that is being sent over the link?

Your logic makes sense, but the numbers don't seem to quite line up with it. For example, I have an ECU that cycles every 15 minutes on a 1 day program. The survey reports that it will produce 17,417 per hour, which would be 4,354 per cycle. But the amount sent over the link is 10,647. The highest output cycle in my program is 7283 (the per hour number is the average), so that doesn't equal 10,647 either.

i gave up to understand all the PI interface because its buggy and crappylagshit...and thell me why i need to wayt xx seconds for every export ...bull...

I have not done a lot of testing on this but I believe the link needs to be rated for the highest single cycle output of the extractor.
yo may average 17,000 units per hour, but the extractor cycles 3-4 times in an hour to reach that number, but the amount gathered with each cycle also varies, usually reducing with each cycle. When a cycle completes the entire amount from that cycle is instantly transported across the link.

However the route does not auto update. so if you set the rout when you had a lower yield, and then got a hot spot spawn which caused you to get a drastic increase in your yield, any cycle that exceeded the amount set in the route any thing over that amount would be lost. This is generally not a problem as generally the maximum an extractor puts out is when you first place it. Keep in mind though you can manually set the routed amount when you create the routs. I have at times found that my links would not support the auto generated max amount, And I did not have any CPU left to upgrade. But when I reviewed the extraction program there was a spike that only put one single cycle above what my link could support. So I manually set the rout to a slightly lower amount that the link could support and only lost a couple hundred units from a single cycle of the entire extraction program.

You can really push the limits of optimization in PI if you really pay attention to the numbers and manually set your routes. I find that by sacrificing a small amount of extracted material from the odd cycle that I can keep my links running at or near 100% freeing up CPU for additional factories or storage while only losing a minimal amount of my extracted P0. As long as the extractors are extracting enough to keep you factories running 24/7 you do not need to worry about getting maximum yield in order to maximize profits.

I never export P0 and rarely export P1. Finding the right planets(even in high sec) I have no problem extracting 2 P0 to feed 2 P1 factories, in turn feeding a single P2 factory with only command center upgrades 4. I only have to haul once a week with daily resets on extractors and I make easily 30 mil a week per character in high sec with only about 30 minutes per week per character spent on PI. That's 60 mil an hour for completely safe, mostly passive income. Considering I have 4 characters doing PI that's 120 mil a week for only 2 hours time interments.
