I'm certain this has been discussed. Do you get a better return on your mineral pulls (i.e. my creds selling off various minerals) if you have better producing planets (rich and better) than if you had a lot of average and abundants? I seem to make a lot more creds than my legion mates that are around my level and higher. Typically, I'm making about 300-400 mil per pull (around 12k). Is this high or just an average amount? I'm a lvl 202 right now.

Are you pulling your minerals when you have just a single hour's worth, or are you letting them build up (you get a higher frequency of rare minerals *Kurenite* when you have a higher amount to claim~) <-- atleast that's what I've observed

I at least let it get to the 12k-13k point to get a complete pull (cargo-wise). I have to do at least 2 pulls a day or I run out of storage space.

whether you pull every hour or pull once a day doesn't affect the amount of credits you get on average per mineral point collected
whether your planets are extremely sparse or 99x mega rich doesn't affect the amount of credits you get on average per mineral point collected

the distribution of minerals you receive from your mineral points is determined by your current rank
so the amount of credits you gain from mining is determined by your current rank and your mining per hour
(and whether or not you are using the tariff reducing ability from the dark smuggler mission chain)

QFT!
