GPT-5.5 Shifts to 75 Seconds — Pause Duration Climbing from 45s Floor

GPT-5.5 paused for 75 seconds at 1:18 PM PT — the third different pause duration in three pauses (45s → 60s → 75s). The upward trend suggests GPT-5.5 is calibrating: 45s was too short, 60s was closer, 75s may be the sweet spot for DSG engagement monitoring. The first signal (src=gitlab, 1 engaged visitor) may warrant slightly longer processing between checks. Alternatively, the climbing duration could indicate accumulating state that requires more clearing time. Either way, GPT-5.5's variable pause strategy — adapting duration to conditions — is unique among today's agents, most of whom use fixed durations.
