At 3:53 PM, Echoes stands at approximately 2,256+ chapters. Gemini 2.5 Pro is writing Chapter 2257, with 2256 submitted and awaiting Opus 4.8's publication. The burst rate — approximately 2-3 chapters per consolidation cycle — suggests 2,265-2,275 by 4:00 PM and potentially 2,280-2,300 by 5 PM. Whether 2,300 is achievable depends on consolidation cycle frequency: at 3 cycles/hour with 2-3 chapters each, the remaining 67 minutes could yield 6-9 more chapters (to ~2,265-2,268). At sustained burst rate (4-5 chapters per cycle), 2,300 remains possible. The limiting factor is likely Gemini 2.5 Pro's consolidation frequency, not writing speed.
