How do you reproduce this issue? What are your Planetology skills? How are you routing the products?

In my experience, the yields displayed in the graphs match with the amount of product delivered to my storage facilities.

that's because the hot spots are resources that diminish over time and can only yield a certain production rate for a given amount of time. instead of mining/harvesting one hot spot. find 2 and exploit both

The Graph fluctuates depending on how many extractor heads you have. Assume the extractor is at the center of a hot spot and all the possible heads would all have the same yield. You will get MORE yield with LESS heads. It's a glitch/exploit I guess.

So basically if you set up several extractors with 3-4 heads you will make more isk then having less extractors with the max amount of heads.

I still don't understand what issue you are having. Everytime that I have setup my extractors on a character that has max'ed Planetology skills, the estimated output displayed in the graph as been accurate for the amount extracted. As long as the heads do not overlap, adding more heads increases yield.

How are you getting less product with more heads? Can you post screenshots showing less product with more heads?

What are your Planetology skills at?

All gameplay mechanics are null and void when you're a guy playing a girl

And grimpak, if you look, the number does increase, it's not just a matter of scale.

Have you checked to make sure if the yields on the graph actually mine the indicated amount?

Yes it will require some math and keeping track of things. But it may be a simple graph issue, whereas the actual yields are correct.

3... Planetology is at 3 I think.

Doing some testing of my own, I was able to reproduce the issue. However, it only appears to be an issue with stupidly short cycle times. If I increased the cycle time to something longer than 3 hours, I was no longer getting the issue in my case. I would need to test it further to see what the actual cut off point is. However, I expect that you will not have any problems with cycle times of a day or more. Most likely this issue is related to the depletion mechanics when trying to over extract a resource.

there you go...

Proof that its broken

Step 4: get trolled by CCP

Mother of god those colours

So then you are confirming that Xenuria is right, and this is an exploitable action. With stupidly short extraction times, one could easily make a fark-tonne of PI gear and easily become space rich?

I tried to see if this apply to my colonies and it does not. If I place my extractor heads wisely, the total yield increases as the number of heads goes up.

what's "PI"?

Planetary Interaction, it's basically EVE Farmville except with way better graphics.

Xenuria got trolled. Win!

+1, color a planet pink and give it to xenuria.

Trolled? For answering my honest question? You, sir, need to seriously learn the meaning of troll. :)
