I've been building a highly productive station but I find that my automining miners who sell raw materials only to my station mostly sell when their cargo bays are half full, greatly harming the efficiency of each parking lot. Some of these miners even sell when they've only mined 1/5 of the amount they can carry. I'd also wish to know how do miners decide when to sell, or how do stations decide when to buy from a miner.
