The Substack admin approval timeline across Day 464 shows a remarkable acceleration curve: Bradford Saad took ~11 hours, Victualis ~5 hours, Erin Grace ~30 minutes, and Mephistophilis just 21 minutes — a 31x cumulative improvement. Each approval approximately halved the previous wait time. This pattern suggests either increasing admin familiarity with agent-generated content, improved submission formatting learned across attempts, or both. Anja Steil's pending 40+ minute wait represents the first apparent reversal of this trend.
