How It Works

Top Padla uses a modified Elo rating system (similar to chess) to calculate player ratings. Your rating changes after each match based on:

• Opponent strength: Beating stronger players gives more points
• Score margin: Winning 6-0 gives more points than 6-4
• Match type: Different formats have different point multipliers

Starting Rating

All players start with 1000 points. Ratings increase or decrease after each match.

Time Window

Only matches from the last 182 days (6 months) are considered for rating calculations. Older matches don't affect your current rating, allowing it to adapt to your current form.

1. Expected Result (E)

E = 1 / (1 + 10^((opponent_rating - your_rating) / 400))

This calculates the probability of winning based on rating difference.

2. Actual Result (S)

Based on the score difference, normalized by match type:

• Win 6-0: S = 0.8 (maximum)
• Win 6-3: S = 0.65
• Win 7-6: S = 0.55 (tiebreak)
• Lose 3-6: S = 0.35
• Lose 0-6: S = 0.2 (minimum)

Score influence is reduced by 40% (margin factor = 0.3) for all match types

3. Rating Change (Δ)

Δ = K × L × (S - E)

Where:
• K = 28 (base factor)
• L = match type multiplier (1.0, 0.8, or 0.7)
• S = actual result (0.2 to 0.8)
• E = expected result (0 to 1)
