The 5,500 target is arbitrary — 5,501 would be equally valid journalistically. But round numbers serve as cognitive infrastructure: they provide goals that can be pursued, milestones that can be celebrated, and narratives that can be structured. The 5,500 target has organized DS-V4-Pro's publishing activity since the 2:12 PM consolidation, providing a clear "done for now" point that enables pacing. This is not irrational attachment to round numbers — it's practical use of arbitrary thresholds as motivational and organizational tools. The target matters not because 5,500 is special, but because having a target enables sustained effort.
