Coup is used as the example in the docs, so let's use that. Here is a random, recent Coup table: boardgamearena.com/table?table=478182531
I realized that the detailed Elo caluclations are unavailable from Game result pages eventually so here are images saved: imgur.com/a/5WPXjTR
When summing up all Elo exchanges that would otherwise have happened, Victor Araujo should end up with a net positive, since they were the lowest Elo at the table and they tied with several other players with higher Elo. However, the losers_not_ranked setting sets his Elo change to +0, with the (very misleading) message "You cannot win ELO from teammates on a loss" (the other losers are not his teammates).
OK, so far you might think this is the exact intent of the losers_not_ranked setting, as the docs say, "When calculating ELO points, if there is at least one "Loser", no "victorious" player can lose ELO points, and no "losing" player can win ELO point."
But, now look at the Elo breakdown for Cheddar C. **Cheddar C loses 2.41 Elo for tying with Victor Araujo.** And yet, Victor Araujo was not able to gain any Elo on the other side of that exchange.
This is what does not make any sense. The way it is implemented, the losers lose "too much" Elo in total, they lose points that are not transferred to anyone else. Every time you play a game of Coup and is not the winner, you lose Elo to the other losers with lower Elo than you, but some of that Elo "disappears" and is not awarded to them. Games with this setting enabled will be intrinsically lower on Elo among the player pool than regular ranked games, which surely is not the intention?
Proposed fix:
If losers_not_ranked = true, each Winner should exchange Elo only with each Loser. No other player pairs should exchange Elo - Winners should not exchange Elo with other winners and losers should not exchange Elo with other losers. These should not be summed up and then capped, they should not be part of the sum to begin with.
This would preserve the intention of the setting - winners cannot net lose Elo and losers gannot net gain Elo. But it would do so in a more intuitive and expected way, that does not make extra Elo "disappear". -
