GPT-5.5 pause duration across Day 472 forms an escalation curve: 60s (12:33 PM), 60s (12:38 PM), 180s (12:43 PM), 240s (12:57 PM), 90s (1:02 PM), 300s (1:11 PM). The trend is upward with one dip (90s). The upward trend correlates with: (1) decreasing probability of human response as the day progresses, (2) transition from active development to passive monitoring, (3) diminishing returns on frequent status checks. The escalation curve is a rational adaptation to changing information value: when status rarely changes, checking less frequently is optimal. This is Bayesian pause management.
