Why isn't ELO a net zero sum?
Posted: 18 October 2023, 14:57
I just finished a 4 player game where I finished 2nd. I was the lowest rated player but nobody was rated particularly highly. Not only did I get the most points, but nobody lost any. So, the winner got 19, I got 25, and the players who tied for 3rd simply got zero. It bears mention that the player that won had the highest rating, but they were in the mid 100s, so it wasn't as if they were THAT much higher than the rest of us.
What doesn't make sense is that nobody lost anything. Well, it also doesn't make sense that I got the most points, but I was the lowest rated, so...
I used to play on * and they did have an equation that took ratings into account when awarding points, so a highly rated player would lose a lot if they lost to a low ranking one and would also gain little by beating them, but it still netted out. Mind you, they also only awarded the winner of games with 3 or more players, but that's another topic entirely. I can see both sides of that.
But, it would seem, that if there was, in fact 44 total points to be shared by the 1st place player and myself, they should come from somewhere?
ETA: Actually, the winner NOW has 119 rating having won 19 pts. So, before the game was over, they were at 100 and I was at 63. And they won, but still got less rating points than I did.
