Methodology
Sightstone Rating
One number for how well a player performed in a game. 1.00 is an average professional game.
Every player in every game gets a rating. It compares their game against everyone else who played the same role in the same season, so a support and a mid laner are judged on what their job actually is, and a 2016 game is measured against other 2016 games.
How it's built
- Six components are measured for the game (table below).
- Each one becomes a z-score against the role's season average, capped at ±3 so one outlier stat can't dominate.
- The z-scores are combined with role-specific weights. If a game has no in-game timeline (LPL, older games), the gold-lead component drops out and the others are re-weighted.
- The result is scaled so 1.00 is average and a typical game lands between about 0.50 and 1.50.
| Component | Top | Jungle | Mid | Bot | Support |
|---|---|---|---|---|---|
| KDA (log-scaled) | 25% | 25% | 25% | 25% | 25% |
| Kill participation | 10% | 25% | 15% | 10% | 30% |
| Damage share | 25% | 15% | 25% | 30% | 5% |
| CS per minute | 15% | 10% | 15% | 20% | 0% |
| Vision per minute | 10% | 15% | 5% | 5% | 30% |
| Gold lead @15 vs lane | 15% | 10% | 15% | 10% | 10% |

- below 0.85 rough game
A season rating is the average of a player's game ratings. The rating doesn't include whether the team won, and it doesn't adjust for opponent strength, so compare players within similar competition. Leaderboards default to the major leagues for that reason. The series MVP is the player with the highest average rating across the series.
