Select an answer to reveal the explanation.
Short Explanation
Variants ran 70/30 for fourteen days, and error rate and revenue-per-space are in CloudWatch. Read those production A/B metrics and pick the winner. Changing weights first throws away the window.
Full Explanation
Declare the A/B winner from the production monitoring metrics over the trial window. That is the monitoring decision, not the original traffic-split configuration. Fraud Detector is not that decision, and changing weights first throws away the window.
