Copa de la Superliga — Home Advantage

1. Home Advantage: How much a team's results improve on their own ground versus on the road — a combined signal from both attack and defence.

2. Scored: Compares goals scored per game at home against goals scored per game away. A positive figure means the team finds the net more easily at home.

3. Defence: Compares goals conceded per game at home against goals conceded away. A positive figure means the team keeps opponents quieter on their own turf.

The combined Home Advantage score is the average of the Scoring and Defence figures, weighted equally.

Goal-based metrics give a sharper picture of home performance than win/loss records alone, since they reflect the margin of each match.
