Margin Total
Points scored minus points conceded, added up. Soccer's goal difference, generalised.
sum(your_score - opponent_score)
Best at
Two-sided scored games where the size of a win carries information.
Where it misleads
Only works for two-sided matches, needs scores, and rewards running up the score.
How it works
Margin Total ranks by cumulative margin of victory (or defeat). Points scored minus points conceded across all matches.
How it works: For each match: margin = your_score - opponent_score. Sum all margins. Positive total means you've outscored opponents overall.
When to use it: For head-to-head scored games where the size of victories matters. Common in sports leagues as a tiebreaker (goal difference in soccer, point differential in basketball).
Watch out for: Only works with 2-sided matches (duel or team_vs_team). Running up the score is rewarded, which some groups may find unsporting. An optional margin cap can address this.
