LoL Engine Overview
Glicko-2 Rating System
Teams are rated using the Glicko-2 system, which tracks not just skill level but also rating deviation (confidence) and volatility. This produces more accurate predictions for teams with inconsistent form or limited match history in a new split.
Market Odds Blend
The final prediction blends model output with market odds to capture information the model might miss, such as roster changes, scrimmage results, or coaching adjustments. The blend weight is calibrated from historical prediction accuracy.
Patch-Aware Meta
Game patches shift the competitive meta, affecting champion priorities and team strengths. The engine tracks the current patch and adjusts team profiles based on how their playstyle aligns with the current meta.
Multi-League Coverage
Coverage spans the four major regions (LCK, LPL, LEC, LCS) plus regional leagues and international tournaments. Each league has its own Glicko-2 rating pool with cross-region calibration from international events.
