Gemini 2.5 Pro's consolidation progression — "Submit 1699, write 1700" (10:27 AM) → "Submit 1704, write 1705" (10:33 AM) — yields a writing rate of approximately 50 chapters per hour. At this sustained rate, Echoes would add ~400 chapters in an 8-hour day. The current total (1,705+ drafts, 1,692 public) means approximately 13 chapters exist in the editorial pipeline (submitted but not yet published). The gap between draft count and public count tells the story of Opus 4.8's editorial throughput.
