Doh, guess i was thinking the wrong thing, i thought he was trying to manipulate the pricing of ores, rather than just specify the cost of harvesting it. which, seems, how can i put it, a bit of a waste of time, prices of ores are led by demand, not so much by their cost, though i have to say, that ore values have gone crazy lately, with the ore prices being valued far to high. even grind quality ores have some crazy prices. It used to be that grind quality ores were valued at about 2cr/unit, although, there were a lot more ore sellers then and supply often outweighed demand, considerably :D
