what a rating means
100 is the average runner in the athlete's pool; a rating of 133 means 33% faster than that average runner. Ratings are distance-normalised and course-adjusted, so a hard course and a fast track land on one number. Each pool (high school boys, college women, middle school…) has its own average, and the HS-equivalent view puts every pool on the high-school scale.
