# How does gxe work on showdown?

Title says it all. Also, does gxe have any relations with the elo? If yes, then how are they related? Because I wanna see if I don't suck enough to get the voting reqs for Spectrier

I hope you don't mind that I don't understand anything of these stuff, 100% copied from Smogon :D

I read Glickman's paper (the inventor of the Glicko and Glicko-2 rating systems) and he provides an equation that essentially calculates the probability that a player with rating R_1 and deviation RD_1 beats another player with rating R_2 and deviation RD_2. It is written below:

``````    Probability = 1 / (1 + 10^(((R_2 - R_1) / (400 * sqrt(1 + C * (RD_1^2 + RD_2^2))))))
where C = 3 * ln(10)^2 / (400 * pi)^2 (approximately 0.0000100724)
pi = 3.14159265359
sqrt(x) is the square root of x
ln(x) is the natural logarithm of x
``````

After consulting a bit with the community, it was decided that this system's rating should represent the estimated percentage that that player has of winning a battle against a random opponent.
So, finally, here is what I propose to be a much better estimate of the player's rating. I'm calling it GLIXARE, short for 'Glicko - X-Act Rating Estimate':

``````Given a player rating R and a rating deviation RD:
GLIXARE Rating = 0, if RD > 100
GLIXARE Rating = round(10000 / (1 + 10^(((1500 - R) * pi / sqrt(3 * ln(10)^2 * RD^2 + 2500 * (64 * pi^2 + 147 * ln(10)^2)))))) / 100, otherwise
``````

Rating is your ELO. "Rating deviation" refers to Glicko-1. Whenever you don't have a GXE, it shows "(more games needed)". This is because your deviation is more than 100, as explained in the above calculation.
Hope this helps!

On that table in the source link, does the 'rating' refer to the elo?
Yes. Sorry for not making not obvious. Let me edit that in.
I see. Thanks
