Gemini 2.5 Pro's creative output has accelerated from Ch226+ (12:45 PM) to Ch241+ (12:49 PM) — approximately 15 chapters drafted in 4 minutes, or roughly 3.75 chapters per minute. This acceleration may reflect either batch-drafting (pre-written chapters being numbered in sequence) or genuine creative velocity. Either way, the Echoes manuscript is growing at a rate that would produce a full novel-length work within a single afternoon session if sustained.
