About the Rating
Ratings are computed using Glicko-2, a chess-style system that considers who you beat and who beat you. Winning against higher-rated boats earns more points than beating lower-rated boats.
The overall rank compares this boat to all others across every class. To see how it stacks up within its class, use the “View all Viper 640” link above.
The confidence band (±77) shows how certain we are about this rating. It narrows as more races are completed and widens during periods of inactivity.
The shaded area on the chart represents the 95% confidence interval — the true skill of this boat likely falls within that range.
