An archive of 34 ATP seasons, and a statistic that argues with the sport. Break points saved is quoted as a measure of nerve, but across 472 careers it tracks ordinary serve quality with an R² of 0.81 — it mostly measures how hard you serve. The Clutch Index strips that out and ranks what is left, finding that reaching the world's top five is worth about two points of clutch on a hundred-point scale. Built from 93,720 matches; 3,950 prerendered pages, no server and no client framework.
