The most comprehensive sports luck measurement system ever built.
Every team's CLS is built from up to 9 independent statistical signals per sport - expected goals, Pythagorean expectation, finishing luck, defensive fortune, injury burden, schedule strength, post luck, red card rescissions, and more. Each signal is z-scored across the entire league, weighted, and combined into a single score from -100 (cursed) to +100 (blessed).

Fans are using CURSD to settle arguments with data.
Wolves at -55 CLS. MINUS FIFTY FIVE. I've been saying we're getting robbed all season and now I have the data to prove it.
Liverpool at -20 despite being 5th?? CURSD literally proves we deserve top 4. Sharing this with every City fan who tells me we're finished.
Finally a site that shows Arsenal are lucky this season. +40 CLS. My Chelsea mates are going to love this one.
Real Madrid +28 luck index hahaha. Sending this to every Barca fan I know. The data doesn't lie, they're getting away with it.

Showed the Tottenham page to my wife. She finally understands why I shout at the TV. -23 CLS doesn't lie. We're cursed.
Les Canadiens are getting absolutely robbed this year. CURSD has the receipts. Sharing this in every hockey group chat I'm in. 🏒
Leeds -35. I'm printing the team page and framing it. This is what I've been screaming about in the stands all year. VINDICATED. 💛💙
Hornets at -89 luck index is the most Charlotte Hornets thing I've ever seen. We don't just lose, we lose UNLUCKILY. Pain.

Frequently Asked Questions
Everything you need to know about the CLS.
What is the CURSD Luck Score (CLS)?
A score from -100 to +100 that measures how much luck has influenced a team's season. It combines expected goals (xG), Pythagorean expectation, and other statistical signals. Negative = unlucky, positive = lucky.
Which sports are covered?
Premier League, La Liga, Ligue 1 (⚽ football), NHL (hockey), NBA (basketball), and MLB (baseball). Each sport uses a tailored model - 7 signals for football, 6 for hockey, 4 for basketball. 🏈 Football (NFL) is coming soon.
Can luck actually be measured?
Yes. Decades of academic research validate these methods. Expected goals (xG) in soccer and Pythagorean expectation in baseball/hockey/basketball are well-established methods for separating luck from skill.
Does the CLS predict the future?
Indirectly, yes. Teams with extreme values almost always regress toward the mean. A 'Cursed' team is likely to improve without changing anything, because bad luck doesn't persist.
How often is data updated?
Daily during active seasons. Data from API-Football (soccer), NHL Official API + MoneyPuck (hockey), ESPN API (basketball), and MLB Official API (baseball).
What is xG (expected goals)?
A statistical model assigning a probability to every shot based on location, angle, body part, and game situation. A penalty is worth ~0.76 xG. A 30-yard shot is ~0.03 xG. CURSD uses xG to build an xG table for each league, comparing expected goals vs actual goals to isolate finishing luck.
How is CURSD different from FBref or Understat?
FBref and Understat show raw xG data per match and per team. CURSD goes further by combining xG with 6 other luck signals (defensive variance, injury burden, schedule strength, shot quality, close-game record) into one composite score. It's not just xG stats, it's a full luck diagnosis.
