Rating goes down... after victory?

Postby Lieutenant Lich » 14 Feb 2016, 18:56

Hello everyone who is viewing this topic.
On February 13th, I had a Rohan game where I managed to kill one commander and my team killed the rest, It was a very good game BUT! After our victory, I saw the "Victory!" sign and exited the game. When I checked my global rating, it went down from 687 to 678. After victory. That's messed up. Check if it is some flaw in the system. I know I left the game AFTER is said victory and all units became neutral. So it can't be that thing.

Don't complain about that which you aren't willing to change.

Your shown rating is the result of actualrating - 3 * deviation giving you the theoretical lowest skill you play at.

Before a game your deviation increases by a small amount and since your game was stacked in the favour of one team when you won you didn't gain many points (if any)

Lets say your deviation increased by 2 and you won 1 point from winning.

Your actual rating would increase by 1 but the reduction from 3*deviation would be -6 giving the impression that your rating had lowered.

Wasn't that unbalanced. I will read more about Trueskill sometime.

matching ratings top to bottom it was
916 vs 619
825 vs 479
687 vs 272
-350 vs -724

a 400 point difference is something like an 80% win chance for the higher player.

Also I've been informed there actually is an issue with the trueskill system at the moment and people are gaining and losing points very erratically. Its being worked on
