Abstract: An improved dispensing system and dispensing routine for multiple ingredient formulas is disclosed. The system includes a controller linked to an actuator, a scale and, a means for imparting movement to a plurality of pumps or conveyors and containers for dispensing the plurality of ingredients. After a formula is selected, the controller acts to at least partially load the pump with the first of said ingredients, reads the scale to account for the weight of the receptacle, calculates the motion of the pump required to dispense the target amount of said first ingredient, and either executes a percentage or portion of the motion of the pump required to dispense the target amount of said first ingredient, leaving a remaining amount or a safety factor in the form of a previously determined <maximum overshoot> value.
