Cybernetics IV skillfarm

Just wondering if someone did the math on this. Is it possible to have a profitable skillfarm with characters having only cybernetics 4 and a +4 implant on optimal remap? Most guides i read mentions cybernetics 5 but I want to know if it can be done with cybernetics 4 with a dash PI for supplement. Cheers!

pi on all 3 alts gievs you allready at least 1B/month. so yes.

He is asking about just buying skill extractors, extracting, selling injectors, and PLEXing the accounts.

what means “with a dash PI for supplement”?

Perhaps you are correct. I don’t know what he is asking then.
