1. The difference is not less than one normal salary movement of the officer’s substantive grade. If the difference is less than one movement of the officer’s actual salary, the acting allowance is the amount of one normal movement of the salary scale of the acting post; and
2. If the officer’s actual salary is the same as or higher than the starting salary of the acting post, the acting allowance is the amount of one normal movement of the salary scale of the acting post.
