What is WPA? Win Probability Added measures how much a specific in-game event shifted the model's predicted probability of winning. A positive WPA means the event increased your win chances; a negative WPA means it hurt them. Values are in percentage points of win probability change, averaged across all games where the event occurred. Events with higher counts are more statistically reliable.
