Rankings Powered by Data

The same family of algorithms used by chess, esports, and competitive gaming — adapted for youth hockey with margin of victory, playoff weighting, and strength of schedule.

How a Rating Changes

After every game, your team's rating adjusts based on five factors multiplied together

What Goes Into the Rating

Six factors that make our rankings more accurate than win/loss records alone

📈

Margin of Victory

A 7-1 win tells us more than a 2-1 squeaker. Score difference is log-capped so blowouts have diminishing returns — no gaming the system.

🎯

Strength of Schedule

Beating a top-10 team is worth way more than beating an unranked one. Every opponent's rating directly impacts your rating change.

🏆

Playoff Weighting

Postseason games carry extra weight. District playoffs 1.5x, Regions 1.75x, State Tournament 2.0x. Win when it matters most.

⏱️

Recency Bias

A hot streak heading into playoffs counts more than a September loss. Games are weighted by how recently they were played.

🛡️

Confidence Rating

Teams with 30+ games have rock-solid ratings. A team with 4 games? Their rating is provisional and ranked conservatively until they prove it.

🚫

Anti-Gaming Protection

Log margin caps, weak-opponent penalties, and conservative ranking ensure teams can't inflate ratings by running up scores or padding schedules.

Two Ways to Rank

Different questions, different answers — both are valuable

📊

Season Rating

Pure algorithmic — our best estimate of each team's true strength based on all game data. Answers: "How good is this team?"

🏆

Playoff Standings

Structural — based on how far each team went in the postseason. State champion is always #1. Answers: "How far did they go?"

When they disagree, that's where the interesting debates happen.

Why This Is Better

vs Win/Loss Rankings

We consider how you win, who you beat, and when you played — not just the final score.

🤖

vs Volunteer Rankings

Data is collected automatically after every game. No weekly updates, no human bias, no politics.

Frequently Asked Questions

📉

Why did my team’s rating drop after a win?

If you barely beat a much weaker team, the algorithm expected a bigger margin. A 2-1 win against the last-place team signals you may not be as strong as your rating suggests.

📊

What do the confidence bars mean?

They show how reliable a team’s rating is based on games played. 5 bars = very confident (30+ games). 1 bar = provisional (under 8 games). Teams with fewer games are ranked conservatively.

🔄

How often do rankings update?

After every crawl cycle. Game data is automatically collected from GameSheet — no volunteers, no delays, no human bias.

🆚

What’s Strength of Schedule (SOS)?

The average rating of all opponents a team has faced. A team with 1650 SOS played much tougher competition than one with 1400 SOS, even if their records are similar.

🏒

Do tournament games count the same as district games?

No. District games are the standard at 1.0x weight. Tournament games are 0.7x because they're often mixed skill levels with back-to-back games. Scrimmages are 0.3x.

🤔

Season Rating vs Playoff Standings — what’s the difference?

Season Rating is purely algorithmic — our best estimate of team strength. Playoff Standings are structural — State champ is always #1. When they disagree, that’s where the debates get interesting.
