Luck Coefficient NEW

Separate indicator · Scale 0-100 · Based on opponent activity

An indicator independent from the Lucky Index measuring how much luck Wisła had during your matches. It analyzes opponent statistics — how well rivals shot, how many chances they wasted, whether Wisła won matches "by luck". A score of 50 means neutral, above — the fan brings luck, below — bad luck.

xG Overperformance — goals above expectations (efficiency vs xG)
Defensive Luck — fewer goals than opponent's xG
Save Rate — % of opponent's on-target shots saved
Lucky Wins — wins despite lower xG than opponent
Low Possession Wins — wins with less possession
Opponent Waste — wasted opponent chances
Pressure Survived — surviving strong opponent pressure
75-100 Talizman
