Detailed Scoring Breakdown
Tier Score (30% weight)
Your ranked tier and LP determine your tier score. Each tier has a base score starting from Iron (100) up to Challenger (1000). Divisions within a tier add incremental points, and LP provides fine-grained differentiation. A calibration factor slightly reduces scores for Iron/Bronze to correct for statistical over-representation in lower ranks.
Win Rate Score (25% weight)
Only your most recent 20 ranked games are considered. Your win rate is multiplied by 1000 to produce the score. This ensures the system reflects current form rather than lifetime statistics.
KDA Score (20% weight)
Your average (Kills + Assists) / Deaths ratio across recent games is normalized against a benchmark of 5.0 KDA. A KDA of 5.0 or higher yields the maximum 1000 points.
Farm Score (10% weight)
This combines CS per minute (normalized to 8 CS/min) and gold per minute (normalized to 500 gold/min). Both are equally weighted and capped at 1000 combined points.
Mastery Score (10% weight)
The average mastery points of your top 3 most-played champions is normalized against 500,000 points. High mastery indicates deep champion knowledge and experience.
Consistency Bonus (5% weight)
This measures how stable your performance is. Lower variance in KDA across recent games yields a higher consistency score. Consistent players are statistically more reliable.
