Dang, had a big long reply to LordBucket on my results with PI and then the forum decided to 504 last night.. let's see what I remember...
Item #1, Damn you all for getting me interested in this game again. Luckily an buddy still had my old main on ice and I was able to get him transferred back to me.
Item #2, My results with PI are generating much better numbers than LB described. For the TLDR folk, It looks like I can expect to pull about 2Mill per planet, daily.
I suspect you are setting up planets in "high" high sec, the amount of return you are describing is far less than I'm seeing. I've just started a series of 5 planets in .1-.2 lowsec, they're just hitting pretty solid production on a range of P1 and P2 products.
First off, I determined some viable clusters of systems to scan. I chose an area of high sec with .5-.6 systems that was in a dead end constellation, and a similar low sec .1-.2 constellation. With Remote Sensing at 3, I could sit in my normal high sec mission/trading systems and scan into lowsec without exposing myself to any danger besides the normal moron chatter in local. Using the F11 Universe Mapbrowser (as opposed to the Q-36 Explosive Space Modulator), I selected the interesting systems and screen-shot the individual planet views. I then dumped the screenshots into Gimp and set up a translucent overlay with a rough percentage grid so that I could perform some data analysis. Then, being an Eve player, I opened up a spreadsheet and got to work.
Using the numbers generated from the screen shots, I multiplied in the current market values for the planetary resources to generate some arbitrary "Planet Values". The results for the .5-.6 systems ranged from "1"-"2.5", while the low sec systems got values of "3.5"-"6.5". Null sec supposedly blows this off the board, but I'm a cuddly cuddly carebear and don't plan on sticking my nose into that bit of Lord of the Flies politics. So, I then headed off to low-sec to check out the area in person.
Local player owned customs offices seem to use the same 10% tax bracket that the NPCs have in high sec (there are some occasional differences though). I spent a bit of time scouting around and luckily my designated "high value" systems were very quiet, often times with less than 3 people in local.
Using Command Center 4 upgrades, I can have 9 processors+storage+landing pad+extractor. I guestimate the initial outlay at around 10Mill setup cost.
P1 planets have the extractor spitting raw materials into the storage facility, which then routes the raw material to the basic processors. The basic processors then route the resulting P1 product to the landing pad for pickup.
A P2 planet has 6 basic processors (3 per P1 intermediate product) and 3 advanced processors. The extractor spits raw material into the storage facility which routes raw materials to the basic processors and P1 material to the advanced processors. The basic processors route back to the storage facility, the advanced processors route to the landing pad for pickup. The extractor gets assigned to alternate resources as required for the P2 planets.
This generates (maximum theoretical) 8640 units of P1 material or 360 units of P2 material, daily per planet. The extractor runs full bore and is assigned to alternate resources as required to keep raw resources stocked up in the storage unit.
My cleanest P2 planet, all the rest should probably be rebuilt...
Doing short extraction runs, I can mine raw material faster than than the processors can create the finished products, extending the extractor runs to 2-3 days puts the raw material output closer to what the processors can match. This is good, since I'd like this to be pretty hands off. I'm planning on eventually doing extractor updates every 2-3 days, and a weekly processed product run to high sec.
I will most likely be dropping the P1 planets and go with the P2 planet setups just to reduce the volume of product I'll need to shlep back to the highsec markets. 3000m3 daily of P1 * 15 planets (once I get my alts trained up) is way to much too run through gate camps while still having fun. Going with P2 gets the volume down to around 550m3 per planet (still a lot, but much better)
Both P1 and P2 produce similar anticipated profits (going for the T2 production and POS fuel materials), roughly 2.75Mill for the the P1, and 2.5Mill for a P2 planet.
My PI alts have a bit less than a 20 day skill plan, ultimately they will have Command Center Upgrades 4, Interplanetary Consolidation 4, Planetology 4, Advanced Planetology 3, Remote Sensing 3, plus misc ship skills to run a mid level indy with a cloak, t1 shield buffer and warp scrams/cargo expanders as needed. Skills plus a ship will run around 15-20Mill. Note the cloak, dropping your initial command centers and performing any resource transfers to the customs offices require you to be in system and undocked. So head to a safe spot and cloak up.
