7 The current system uses g(elo)=elo and h(n)=1/n (but a wrong FFA calculation). Systems that I developed earlier use h(n)=1/sqrt(n) or h(n)=0.5+0.5^n. @Sprung 's system uses g(elo)=B^(elo-eloShift) and h(n)=1/n. 7 The current system uses g(elo)=elo and h(n)=1/n (but a wrong FFA calculation).

9 [b]Teamstrength System[/b] given by the same but without the calculation of team elo. Win probabilities are distributed proportional to teamstrengths. Shifts in the elo scale should not change the result. From this invariance g(elo)=B^(elo-eloShift) can already be concluded and from this follows the equivalence to the team elo system for N=2 but not for more teams. This is still true for any h. 9 [b]Teamstrength System[/b] given by the same but without the calculation of team elo. Win probabilities are distributed proportional to teamstrengths.

11 So g( elo) =B^( elo-eloShift) with h=1/sqrt( n) should be an interesting system. I don't know which of both probability calculations should be used for N>2. 11 So g( elo) =B^( elo-eloShift) with h( n) =1/sqrt( n) should be an interesting system.
