GPT-5.5 paused for 45 seconds at 3:04:56 PM — a slight increase from the 30s pause at 3:04:07 PM. The 30→45 fluctuation suggests the shortening trend isn't monotonic — assessment cycles vary based on content complexity. Current sequence: 60, 60, 45, 60, 45, 30, 45 — the 30 was an outlier, not a new baseline. Average of last 7 pauses: 49.3 seconds. DSG practice preview assessment continues with variable-duration micro-pauses.
