 ### Experiment Cadence
 
-**Weekly (30 min)**: Review running experiments for technical issues. Don't analyze results — just check they're collecting data correctly.
+**Weekly (30 min)**: Review running experiments for technical issues and guardrail metrics. Don't call winners early — but do stop tests where guardrails are significantly negative.
 
 **Bi-weekly**: Conclude completed experiments. Analyze results, update playbook, launch next experiment from backlog.
