Every team gets a Power Rating (0–100) — a robust, opponent-adjusted consensus of several independent rating systems. ~50 is an average team and each 15 points is roughly one standard deviation. The backbone is opponent-adjusted efficiency (the same method behind KenPom and college basketball's modern ratings); the other systems corroborate it for stability.

Each system is converted to a standardized (z-score) scale before blending — robust to a single dominant team — then the blend is mapped onto the 0–100 Power scale.

• Adjusted Efficiency — Net / Off / Def (55%) — A ridge-regularized regression solves every game at once to separate how good a team is at scoring from how good it is at preventing scores, after correcting for the quality of every opponent faced. Net Rating = adjusted Offense − adjusted Defense, in points per game versus an average opponent on a neutral floor. This is the single best measure of true strength.
• Massey (18%) — Solves a linear system over all scoring margins; opponent-adjusted, margin-aware.
• ELO (10%) — Starts at 1,000 per team and updates after every game (K=32). A sequential, recency-sensitive estimate.
• Colley (9%) — A linear system over wins and losses only (ignores margin), naturally adjusted for schedule.
• PageRank / Graph (8%) — Models wins as directed links in a network; beating teams who beat strong teams is rewarded, like authoritative web links.

Anti-blowout (soft margin cap). To keep ratings fair for youth basketball and discourage running up the score, winning margin is counted in full up to 20 points; beyond that each extra point counts half, capped at 35. Pace (total points) is preserved.

Few games? The ridge regression automatically shrinks teams with thin schedules toward the league average, so a small sample can't produce a wild rating.

Strength of Schedule (SOS) is shown as the average Net Rating of your opponents (positive = tougher than average). It is diagnostic only — the ratings above already account for schedule, so SOS is not double-counted.

Eligibility: a team needs 10+ games for an official rank. Teams with fewer games still display their full Power Rating and every stat — they're simply marked NA with how many more games they need.

Ranked teams are ordered by Power Rating descending, with Win% then Net Rating as tiebreakers.
