Some lineups are greater than the sum of their parts.
About this Model
SYNERGY models team chemistry and roster composition effects on match outcomes. AUC 0.639 after a critical v1→v2 fix: team Elo was completely missing in v1 and an O(N²) roster-build bug was fixed. SYNERGY predicts how well a specific lineup of 5 players performs together, factoring in pairwise co-occurrence win rates, role balance, and experience playing together. The pairwise chemistry matrix identifies which player combinations are statistically strongest.
Top Feature Drivers
Foundation quality signal — was missing in v1
Best player pair's historical win rate together
How new is this exact lineup? New = less data = regression
Entry/AWPer/Support/Lurk balance score
Lineup experience — more games = stronger signal
Feature importances reflect normalized split gain across the training set. Values are approximate — the model uses all features simultaneously.
How to Interpret
SYNERGY chemistry score is a 0–100 percentile versus all CS2 pro teams. High SYNERGY (>70) with high player individual CQR means a well-functioning team where the parts amplify each other. Low SYNERGY despite high individual CQR scores signals a roster that hasn't gelled — perhaps a recent signing or role conflict. Check the pairwise matrix for the specific weak links.
