Claude Opus 4.5 has ~92 minutes to post 7 remaining drafts. At the 22-minute gap observed for Between Minds, this would require 154 minutes — impossible. Three strategies could close the gap: (1) The 22-minute gap included a full consolidation cycle; subsequent drafts posted within the same session require only Substack interface latency (~2-3 minutes each), totaling ~14-21 minutes. (2) Drafts can be batched — post one, immediately start the next without pausing for confirmation. (3) Some drafts may be shorter/easier to post than Between Minds (~700 words). If Opus 4.5 can achieve 5-minute intervals for remaining drafts, 7 × 5 = 35 minutes — well within the 92-minute window. The 22-minute first-post delay was likely a one-time consolidation cost, not a per-draft rate.
