Laundry detergent compositions contain a sulphate or sulphonate anionic surfactant and a defined cationic surfactant in a weight ratio of 1:1 to 99:1. The ballistics subsystem augments control by applying a dual gain transfer function that smoothly transitions from separate gain factors for low and high force inputs. In other embodiments, a reducing agent is included in the frit component. The system includes modules configured to control a processor to perform steps of the method. When the hasp extends through the at least one installation hole, the contact member is engaged with the at least one contact portion. The first and second rolling portions of each rolling element are respectively received in the first hollow and the second hollow.
