1. What is ELO Win Probability?

The ELO win probability estimates the chance of winning a match against an opponent based on the difference between your ELO rating and your opponent's ELO rating. This system is commonly used in competitive games like League of Legends.

2. How Does the Calculator Work?

The calculator uses the ELO probability equation:

\[ P = \frac{1}{1 + 10^{(R_{opp} - R)/400}} \]

Where:

\( P \) — Win probability (0 to 1)
\( R \) — Your ELO rating
\( R_{opp} \) — Opponent's ELO rating

Explanation: The equation shows that a 400-point ELO difference means the higher-rated player has a 10:1 expected win ratio against the lower-rated player.

3. Importance of ELO Calculation

Details: Understanding win probabilities helps players assess match difficulty, track skill progression, and set realistic expectations for competitive matches.

4. Using the Calculator

Tips: Enter both your ELO rating and your opponent's ELO rating. The calculator will show your estimated win probability as a percentage.

5. Frequently Asked Questions (FAQ)

Q1: What's considered a significant ELO difference?
A: A 200-point difference indicates about a 75% win probability for the higher-rated player.

Q2: How accurate is this for League of Legends?
A: While the ELO system works well generally, actual win rates may vary due to team composition and other factors.

Q3: How does this relate to LP in League?
A: LP (League Points) is derived from your hidden MMR (Matchmaking Rating), which functions similarly to ELO.

Q4: Can I use this for ranked team matches?
A: For team matches, you'd need to average the ELO ratings of all team members.

Q5: Why is the constant 400 used?
A: This scaling factor determines how quickly win probability changes with rating difference. A higher number would make the system less sensitive.
