Can somebody please explain to me how expertise molecules work? I am currently in bronze league where they come into play. The rules state that, whenever a player develops a sample at the laboratory...
"... the player acquires molecule expertise: the robot will need 1 less molecule of the type specified by the sample for producing all subsequent medicines."
So, suppose that at some point I have accumulated x expertiseA points. Does that mean I subtract x from my subsequent typeA molecule costs? Or I just subtract 1?
I am asking this question, because I have observed that whenever my bot develops a sample, some molecules are sometimes left in my bot storage. I think it has to do with bad expertise handling, but I need to know exactly how these expertise points work to fix the problem.
