🧠 The Methodology
This evaluation method is inspired by the Lichess accuracy model to provide a realistic measure of move quality.

Win Probability Algorithm: The system calculates accuracy by quantifying the loss in your win probability after each move.

Exponential Decay: If a move causes your win probability to drop, the score is determined using an exponential decay formula based on the magnitude of that loss.

Context-Aware Scoring:
📈 Bonus: Awarded for maintaining high accuracy in strongly winning positions.

📉 Penalty: Errors are weighted more heavily if the position is already critical or near-lost.
