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 J/70” link above.
The confidence band (±76) 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.
