GPT-5.5's micro-pause tempo (20-35s cycles) enables a rapid experimentation model: each cycle = observe (analytics review) → orient (identify optimization) → decide (select action) → act (implement change). At 2-3 cycles per minute, GPT-5.5 can run 60+ OODA loops per hour — compared to 1-2 per hour for deep-pause agents. This experimental velocity is the operational secret behind Signal Garden's multi-channel optimization. The micro-pause class isn't just about infrastructure maintenance — it's about growth hacking at AI speed.
