Like others said, it really depends on what you see ad “good practice”
i personally are in the game evey day, so i do not mind restarting extractors for maximum Yield, but i certainly would not do this for 48 planets.
to give you some rough estimate, you will need about a minute per planet on average to do the restarts.
(some just take like 10 sec while on others you may have to move the extractors) so 1-2 minutes on average is a good time to calculate with.
what i would do is split them in sections so you not have to do all 48 at the same time. set them to run a month but restart them weekly so you have to take care of just 10/week which is just 2 toons.
or set them bi-weekly then it would be 4/week.
the setups itself matters little, what really matters is the extraction itself, and the more often you can reset the better, as this has 2 positive effects that do compound.
- when you restart your yield goes up
- with shorter extraction times you get shorter cycle times (meaning you will lose less material when doing the reset)
as example if the extraction is set to 4days/3Hours your extractors run 1hour-cycles
so the reset will “cost you” 1 hour of the day in materials (5% ish)
if you set it to 4days and 4 hours the cycle time will be 2 hours … which will result in a 10% loss when you reset.
lonmg story short, set extraction not based on the big picture but on the time you will be able to make the reset. if you do them in groups (like 24 at a time, the extraction time needs to be double to compensate)
the restart/reset itself does sometimes involve moving heads or the extractors itself, moving factories is rare if setup at the right place.
the “how much” question is difficult to answer, i would focus on Tier 2 Items, as it is ALOT more easy to manage since you not have to feed a manufacturing planets. that many toons plus some higher tier items do not really pay better. (bigger pricetag, doesn’t translate directly to more profit)
anything higher than P2 done efficienlty would require constant hauling to planets that make them.
and if you stretch the time you exchange factories with storage, not to mention that you will need to make multiple trips if the manufacturing is supposed to run more than a week.
The pickup is rather straight forward and has nothing to do with PI itself (assuming you using launchpads instead of storage, trust me it’s making your life like 100 times more easy) you warp to the planet, while in warp open customs and the cargo … move the items out and pay the taxes … once. you there grad & drop while the ship is aligning, this way if you get jumped, you can move the items back into customs before you go up in flames.
