I am for merging the FFA and Solo formats Rating wise and game wise and with Hest’s proposed formula in everything except Antichess. Antichess should still offer two 1v1v1v1 options, FFA and Solo. Furthermore, Antichess should be listed under variants leaderboard with three separate ratings: Solo Antichess, FFA Antichess, and Teams Antichess.
My current suggestion the following:
If lowest opponent is 1500 or less, make X range from 0 to 3/7 based on rating average, asymptotically so that a 1500 never experiences second as negative, 1800 lowest player from 0 to 5/7 based on rating average, and 2100 lowest player from 0 to 1 based on rating average.
I hope that’s not too complicated
I see the point of your exceptions and I agree that x=3/7 is an important treshold because that's where 2nd place goes from positive to negative rating change. If I understand you correctly, you want to follow the same graph as we currently use in FFA (was it a tanh?) for all ratings, but if one players is rated lower than 1500, x cannot cross 3/7.
We would need to decide at what point x=3/7, maybe at 1800 or 1900 rating average.
i like the old wta format. ffa for low rated players and solo for high rated players
