A print job received by a printing system has subsets of items. Multiple items are printed on each sheet. Finishing devices of the printing system are limited to processing a single subset of the items at a time, causing printing devices to wait skipped-pitch delays. An unadjusted number of machine-hours to complete the print job is determined based on continuous printing without interruption. A skipped-pitch delay is assigned to each of the subsets of items based on the number of sheets used to print each of the subsets of items. A revised number of machine-hours to complete the print job is calculated by adding the total skipped-pitch delay for the print job to the unadjusted number of machine-hours. The number of the printing devices and the finishing devices to use to complete the print job is determined based on the revised number of machine-hours.
