A method for controlling an amount of material transferred in a system having a plurality of material feeds and concurrent material transfer periods. The method comprising steps of: supplying each of a primary material having a target weight and a secondary material, to a receiving vessel; determining a decision threshold; feeding the primary material to the receiving vessel, feeding the secondary material into the receiving vessel as or after the primary material begins feeding and before the decision threshold, determining a feed status of the primary and secondary materials at the decision threshold; changing the feed status of one of the primary or secondary materials at the decision threshold; and feeding only the primary material within a feed alone time period until the target weight amount is fed.
