Power Rankings U18 AAA

Every team begins at an identical baseline Power Index of 1500. Between seasons, ratings revert toward the 1500 league mean so each new roster earns its standing on the ice.

Ratings update after every game based on the quality of the opponent. Beating a higher-ranked team earns a larger boost than beating a lower-ranked team, and upsets result in a larger rating transfer.

Margin of victory is scaled using a diminishing square-root curve (√Goal Diff). Decisive wins are rewarded, but running up the score in a blowout yields minimal extra rating points.

A regulation win awards 100% of the game outcome credit, while an Overtime or Shootout win splits the outcome credit (75% to the winner, 25% to the OT/SO loser) to reflect a tightly contested game.

Regular season and tournament round-robin games carry standard weight (1.0×), while elimination and playoff games carry a 1.5× multiplier to reflect championship play.

Because every game exchange accounts for the opponent's rating, a team playing a tough schedule is never unfairly penalized for close games against elite competition.
