Scoring System
The scoring system is designed to evaluate user performance across all fight cards they participated in. Each fight card consists of multiple fights, and users make predictions for each fight. The system calculates scores based on the accuracy of these predictions.
User performance currently contains two metrics: totalPoints and totalScore. These are running totals of all participation records for the user.
A participation is defined as a user's full prediction entry for a fight card. It requires the user to have submitted predictions for all fights on that card.
How It Works
When a user participates in a fight card, they make predictions for each fight. Each prediction has three fields: winner, outcome, and hasKnockdowns. The system evaluates these to compute the user’s performance.
Each participation calculates two values:
- predictionPoints: Total points from all predictions on the card
- score: A percentage based on prediction accuracy
Calculating predictionPoints
Each field in a prediction has this scoring system:
| Field | Correct | Incorrect |
|---|---|---|
| winner | 10 | -1 |
| outcome | 10 | -1 |
| hasKnockdowns | 10 | -1 |
MAX_POINTS_PER_PREDICTION is 30, meaning all three fields are correct.
MAX_PREDICTION_POINTS is calculated by:
MAX_PREDICTION_POINTS = number_of_fights_on_card * MAX_POINTS_PER_PREDICTION
Calculating score
The final score is calculated using this formula:
score = (predictionPoints / MAX_PREDICTION_POINTS) * 100
A perfect card gets a score of 100.
Tying It All Together
When a user participates in a fight card:
- Evaluate each prediction
- Calculate
predictionPoints - Calculate
score - Store the

Example
Scenario: A fight card has 3 fights. The user predicted:
- Fight 1: All correct
- Fight 2: Only winner correct
- Fight 3: All incorrect
| Fight | Winner | Outcome | Knockdowns | Total |
|---|---|---|---|---|
| 1 | 10 | 10 | 10 | 30 |
| 2 | 10 | -1 | -1 | 8 |
| 3 | -1 | -1 | -1 | -3 |
Total:
predictionPoints = 30 + 8 - 3 = 35
Max Points:
MAX_PREDICTION_POINTS = 3 * 30 = 90
Score:
score = (35 / 90) * 100 = 38.89
Participation Record:
` "predictionPoints": 35, "score": 38.89 `
