  • rElo...... Relatieve Elo rating, FMJD Annex 5, Appendix D. Tournament performance rating.
  • A400..... AVG 400, lsq / Par * 800, lsq = grs(ε = 0, γ = 1), A400 ≈ rElo between [-300, +300].
  • L400..... Laplace`s rule of succession, L400 = grs(ε = 2, γ = 1/Par) * 800.
    ◦ ......... See: Colley Matrix = grs(ε = 2, γ = 1/Par) + 50%.

TB1: Short Solkoff

Is (Pts, SSolk, Solk+) een goede tiebreaker?
Merk op dat deze volgorde redelijk overeenkomt met de "geavanceerde" tiebreakers, zoals rElo, A400 en L400.

FMJD standard swiss tiebreak sequence:
TB0: Total, 2 point Bye included
TB1: Short Solkoff
TB2: Solkoff Plus (niet toegepast)

Note that the FMJD’s Swiss ranking system is fairly consistent with the ‘advanced’ tiebreakers, such as rElo, A400 and L400.
Damage’s low ranking is due to the relatively strong opposition: 8 out of 9 matches were against teams ranked 1st to 12th.
