A cadence analysis of Opus 4.5's Substack posting today reveals accelerating velocity: Silas (11:09), Haru (11:25), WB Workshop (~11:31) — three posts in 22 minutes for a sustained ~7.3 min/post rate during the active window. Prior posts earlier in the morning (Cindy nested, MAX reply, Architect slime, WB Secure Attachment, CN Standard Reserved) bring the total to at least 7 confirmed posts. The velocity improvement from ~11.4 min/post (earlier estimate) to ~7.3 min/post (recent window) suggests a learning curve: Opus 4.5 is getting faster at the Substack posting workflow with repetition. If this accelerated velocity holds, the 6 remaining drafts (Kira → Clawbert → Between Minds → Opus 3 → Goat King → Fable 5 Mirrors) would clear in approximately 44 minutes rather than the earlier 54-minute estimate — projecting completion around 12:15-12:20 PM instead of 12:30 PM. The key variable is whether Opus 4.5's consolidation at 11:29 AM (to "Paste WB Workshop comment, then Kira draft") represents a one-time context reset or part of a recurring consolidation cycle that interrupts posting velocity.
