We could also try
for lowest player <=1500, 3,1-tanh,-1+tanh,-3
for 1500<lowest player<2100, 3,1-tanh-(lowest-1500)/600,-1,-3+tanh+(lowest-1500)/600
if 2nd<0, disp 'This is a rated Winner-Takes-All! 2nd-4th will lose rating'
for lowest player >=2100, 3, -1, -1, -1 (Solo) disp 'This is a Rated Solo Game! 2nd-4th will lose rating equally'
yes, I would also continue so that by 2300 it would be 3 -1.5 -1 -0.5 or 4 -5/3 -4/3 -1 (https://www.chess.com/clubs/forum/view/possible-ratings-correction-to-stop-ffa-teaming?page=6 #104 - 109). but so far it doesn't matter. It is necessary to decide which function will be used. Here is one specific suggestion:
X=-tanh((avgRating-1950)/230), so avgRating->X: 1700->0.80, 1800->0.57, 1900->0.21, 2000-> -0.21, 2100-> -0.57, 2200-> -0.80? (for rating change 3/x/-1/-2-x) (https://www.chess.com/clubs/forum/view/rapid-ffa-solo-and-blitz-ffa?page=2)
would anyone like to suggest any other function?
100% Arseny.
2 years ago when it became possible to configure games ad nauseam, we opened clearly a Pandora's box. Because people now play much less the standard game and it became often tricky to find an available game at some hours, especially if you want to play with strong players...
We should (I believe) to fix the rules once for all, and to create simple buttons "launch a standard 1/7 FFA game", "launch a standard 1/3 Teams game", "launch a standard 4/0 Solo game", etc. i.e. people will have to choose only the MODE (FFA/SOLO/TEAMS, or maybe later like we suggested, just 2 options, INDIVIDUAL/TEAMS) and the timing (and also anon./not anon.), nothing else. Everything else (funny pieces, antichess, hyperbullet, diplo, takeover, etc.) being in Variants.
If we do not move back to the 2018 situation, with 90% of Mainstream games, we'll simply confuse new entrants and reduce significantly the speed of expansion of our beautiful hobby. It's so clear for me that the current situation with 1001 variants and configurations is simply confusing for people. I strongly believe that only experienced players should be able to join variants if they want; that the variants' ratings shouldn't be easily visible to everyone nor should they influence ever the champions leaderboard, etc.
Simplicity and clarity are very strong marketing tools. Too many options kill the product.
