    Is there a document around that lists the # of rounds needed to fairly find a winner based on the # of players.

    My Friends told me some numbers a week or so ago and I forgot. (Much better memory when its written down at my age)

    round up log base2(number of players)

    ie use the number of digits in the equivalent binary number.

    Here is what DCI said the rounds for swiss Pokemon should be.

    (by Number of Players)
    Number of Players Number of Rounds
    17–32 players 5 rounds of Swiss
    33–64 players 6 rounds of Swiss
    65–128 players 7 rounds of Swiss
    129–226 players 8 rounds of Swiss
    227–409 players 9 rounds of Swiss
    410+ players 10 rounds of Swiss

    5 rounds of swiss seem to be working for me in the 33-64 player group

    Also remember that historically, we've added an extra round to ensure a clear Top 8 Cut. With the elimination of the "Adjudicated Win," this may no longer be necessary. As usual, your mileage may vary. We've been using the old WotC System with the extra round, and have had no problems.

    As far as I know, what I posted is with an extra round added. The document I took that off of is called "Pokemon Age-Modified Swiss Pairing System" and was released back in Feb. of last year.

    The fist lines of this document says:

    So I always thought these were the correct amount of rounds for Pokemon.

    upto 2 players! 1 round to determine winner
    upto 4 players 2 rounds
    upto 8 players 3 rounds
    upto 16 players 4 rounds
    upto 32 players 5 rounds
    upto 64 players 6 rounds
    upto 128 players 7 rounds


    note that it is a good idea to do more than the minimum number of swiss to reduce the effect of lucky pairings in the first few rounds.
