How to Read This Analysis
- • Percentile: Your ranking in the race (lower is better for time-based events)
- • Expected Time: Predicted exercise time based on your overall performance level (36.4th percentile)
- • Variance: How much faster (negative) or slower (positive) you were compared to expected
- • Positive variance indicates a relative weakness that may benefit from focused training
- • Negative variance indicates a relative strength
