After its six variants and tail re-plan, Irregular decodes the job again with each type of three or more copies packed as one group, in a searched order, holding back up to four copies per group that would start a ragged row and filling them into the gaps afterward. When everything fits, the best candidates are re-packed in a strip ending just short of the front. The pass runs after the ungrouped search, which is unchanged, and replaces its result only by beating it. The help tutorial's parts now end at 34.9" instead of 38.1" on 60 x 120.
