It should be appreciated that if step 1 or step 3 may not be synchronized with step 2, for instance due to a non compatibility of the resulting percentages with the actual processing capacities, the sequencing regime 264 may be appropriately adapted, for instance by selecting any default value, for instance, selecting {HEAD ~ an alternating supply} for {TAIL ~ the corresponding process step}
