Since I was reporting only the case of six players each with equal ghost ratings of G, and a seventh with a ghost rating twice as much, 2G, I instantiated the "$grSum" in the code with 8G (1*2G + 6*1G). In your formulae, you have both that factor of 8, AND the factor formed of sum of GRs "(P_GR + (n-1)*O_GR)". A clue is if you look at your computed results, an SOS adjustment of over 200 if a 100 rated player solo'd a single SoS game against 6 other 100 rated players would result in that player's rating jump to 300 - wow!

VonEconomo wrote: ↑Wed Nov 08, 2023 3:00 pm If you give different people different stakes in the same game, those players with higher stakes will obviously have more on the line. If most games are usually populated by newer accounts anyway, what incentive is there for better players (not myself, obviously) to join games where they could only hope to stay relatively stable ratings-wise.

So, if points and GR become more similar (GR becomes more visible, used to bet, etc), then the main difference is that the bet size would become different between each player. I'm worried that it would affect games more than it should. This seems unlikely to me. Once the pool is established there's no changing it. Every player has an incentive to score as much as possible once they enter the game regardless of the pool size or who contributed what. It would be a funny press strategy to try to say "I contributed more, therefore give me centres x, y, z" but it wouldn't actually make more sense than "cede the game to me, I'm a more experience player than you" would. No one who is any good at the game would indulge such a demand unless it were actually otherwise warranted by the state of the map.
