That is, as the discount is increased in steps, the cost to the Postal Service of sorting the mail that becomes workshared on step 4 is probably greater than the cost of sorting the mail that becomes workshared on step 3. This assumption will be relaxed in Part III below, where larger discount changes are considered.
