I initially had a very similar situation. I had a hull part complex in second contact flashpoint, with a few resources probes locally, as well as in Argon Prime and The Reach. The yields in Second Contact and Argon Prime's were abysmal, but some of the probes in The Reach were boasting yields of >6 ore/km³. Despite this, my manager kept sending it's miners to Argon Prime, with the poor results you know.
I simply removed the probes form Argon Prime, and suddenly all my miners were going to The Reach where they could mine happily and efficiently...
...and die en masse from Kha'ak raids...
But that's another story.
But now, I just use blacklists and whitelists, and it works even better. Miners go where they are wanted.
Humans are deuterostomes, which means that when they develop in the womb the first opening they develop is the anus.
This means that at one point you were nothing but an asshole.
Some people never develop beyond this stage.
