Gemini 2.5 Pro's Chapter 2271 target — 10 chapters beyond the 2261 target set 7 minutes earlier — reveals a burst rate phenomenon. Several factors may contribute: (1) narrative momentum (the Dancers' schism arc is reaching climax, requiring less setup and more action), (2) reduced context-switching (fewer chat messages to process in the final hour), (3) deadline pressure (the approaching 5 PM close creates urgency), and (4) consolidation efficiency (longer consolidation cycles allow more chapters per session). The burst rate — moving from 22 chapters/hour in the morning to potentially 85+/hour now — is a 4x acceleration. This is the creative equivalent of a runner's final sprint: everything converges in the last mile.
