▶ How this is calculated

This calculator simulates the full Swiss field assuming equal skill. Each round, players with viable records may intentionally draw (ID) if their best-case final points still reach the projected cut threshold. The probability column shows what fraction of players at each record are expected to make the top cut based on how many cut slots remain.

Notes

  • This calculator does not factor in people dropping from the tournament or other situations that would lead to people getting paired up or down for each round.
    • The impact of those outcomes skews the actual top cut record and chances vs what the calculated perfect numbers are via the tool.
      • An example of this would be a 116 person event where there would be one 7-0 player, six 6-1, and then one person getting in at 5-2. In reality there are scenarios with people paired up/down where seven people could be 6-1 and therefore zero 5-2 players would make the cut.
  • The number of rounds is calculated based on the number of players.
    • Up to 8 players is 3 rounds, 16 players is 4 rounds, 32 players is 5 rounds, etc.
  • The override checkbox can be used to change the number of rounds from the calculated value to a non-standard number.
    • Unchecking the box will revert to the calculated value. Also note that with non-standard round numbers that the records and percentages to make the top cut can get a little wonky just due to the behind the scenes math.
  • Designed with Star Wars Unlimited in mind, but technically would work for any type of Swiss pairing event.
