Tiebreak Systems Overview

1. Modified Median System

• Definition: Used when players tie with an even score (exactly half of the maximum possible score).
• How it works:
  • For players with even scores: Exclude both the highest- and lowest-scoring opponents’ scores.
  • For players with non-even scores:
    • If tied with a plus score: Disregard only the lowest-scoring opponent’s score.
    • If tied with a minus score: Disregard only the highest-scoring opponent’s score.

2. Solkoff System

• Definition: Similar to the Median system, but no opponents’ scores are discarded. All opponents’ scores are included in the calculation.

3. Cumulative System

• Definition: Adds up the cumulative (running) score for each round.
• How it works:
  • Example: If a player’s results are win, loss, win, draw, loss, the cumulative scores per round would be 1, 1, 2, 2.5, 2.5. The total is 9 (1+1+2+2.5+2.5).
  • If another player’s sequence is 1, 2, 2.5, 2.5, 2.5, the total is 10.5 (1+2+2.5+2.5+2.5).
  • The player who scores earlier generally has a higher tiebreak, as they likely faced tougher opposition later.
  • Adjustments:
    • Subtract 1 point for each unplayed win or full-point bye.
    • Subtract 0.5 point for each unplayed draw or half-point bye. 

4. Cumulative of Opposition

• Definition: Calculate the cumulative tiebreak points for each opponent (as above), then sum these values for all opponents.
