Performance Trends Over Time

Explore the visual trends of performance scores and updated ratings across different events. This graphical representation helps in understanding the progression and fluctuations in performance over time.

Ratings are dynamic estimates, representing a range of potential future performance outcomes. The box plots above illustrate these ranges, with the red dotted line indicating the "Performance Score" and the solid blue line showing the "Updated Rating". A performance score falling outside the expected range can lead to significant adjustments in the updated rating, reflecting the dynamic nature of performance evaluation.
