So anyone looking closely might notice that on the PS website ladder pages (the ones outside of the sim, which I assume no one looks at), there's a new column, WCAO:

WCAO is the result of me staring at the GXE formula and wondering if a minor adjustment might improve it.
So, GXE, if you were wondering, is just the Glicko win-chance estimate for winning a battle against a player with 1500±130 rating – in other words, the win chance against a random opponent.
WCAO is the Glicko win-chance estimate for winning a battle against a player with 1500±0 rating – in other words, the win chance against an average opponent.
If you're a good player, playing a good player instead of an average player is going to decrease your win chance more than playing a bad player instead of an average player is going to increase your win chance. So WCAO scores will be more spread out than GXE scores, so small differences between player skill will be more noticeable.
I also took the opportunity to make the name of the rating much clearer in terms of what it actually means: "Win Chance vs Average Opponent" needs less explaining than "Glicko X-Act Estimate".
Thoughts, feedback, etc?
