Changing ELO points for cooperative games

[ufm]

I'm sure it's possible to make ELO reflect the winrate of a cooperative game.

Your idea is still impossible to implement as the game backend cannot read player ratings (BGA framework does), so:

It means that what you are proposing is not doable. We dont have access to elo as game developpers.

So who does have access? To use two examples:

A. Currently: in Bandido you get +1 ELO for winning; and +0 for losing.
Question: Can you not change that to +10 for winning and -10 for losing?

B. Currently: in Hanabi you get +X ELO for completing. X depends on the variant, the average ELO of the team, and the score.
Question: Can you not change this formula to be more similar to a 1v1, and ever non-perfect game being negative ELO?

Among regular developers, no one.

A. Currently: in Bandido you get +1 ELO for winning; and +0 for losing.
Question: Can you not change that to +10 for winning and -10 for losing?

It is already possible and some games are doing so, but your idea is completely different from such simpler computations:

1000 ELO points = 100.0% chance;
300 ELO points = 30.0% chance;
50 ELO points = 0.50% chance. (etc)

B. Currently: in Hanabi you get +X ELO for completing. X depends on the variant, the average ELO of the team, and the score.
Question: Can you not change this formula to be more similar to a 1v1, and ever non-perfect game being negative ELO?

It's hard to define the 'accurate' formula for every score and setup after all. Your suggestion is too vague to be carried out.
