A team runs a canary deployment: 5% of traffic to new model, 95% to champion. After 48 hours, the new model achieves better accuracy (+2%) but worse P99 latency (220ms vs. 90ms champion). The team's SLA is P99 < 200ms. The product manager says "2% accuracy is worth it — can we tune the new model to meet the latency SLA?" What is the correct response?
