This is another MrRoboto post that I appreciate very much.
@MrRoboto said in League General Discussion Thread:
While some strategic choosing of opponents might lead to a higher ELO in the short run, long-term ELO can’t be “gamed”. You will end up where you belong, eventually.
Yes.
2) K-factor (sensitivity)
@gamerman01 said in League General Discussion Thread:
I eliminated range 6-10 games and just made 6+ to 50 sensitivity as it was for 11+ before.
I’m actually not very fond of that change.
Right now, game 6 has a K-factor of 90 while game 7 has a K-factor of 50. Just as an explanation: Against an equal opponent, game 6 would award ± 45 points, while game 7 gives ±25. That’s a HUGE jump. Game 6 is almost double worth as game 7.
Yep. Playing around before the new year starts. K factors can be tinkered with for at least a month, if not more, into 2024 in my opinion. It’s not like we’re going to change them next December until the ratings are desirable for us. We’ll settle on some scale before long. Higher k factors early, declining over # of games played, and nothing crazy, is what I want to see. No arguments otherwise.
I’m MUCH more in favour of a gradual K-factor decline.
That’s cool
The only reason I haven’t implemented it yet is because I have to adapt the formula but I will probably do it later today.
Awesome
3) Counting at the beginning or the end
TLDR: The difference is negligible and it doesn’t really make a difference to count at start or beginning.
This.
It’s easier to record the resignation date when the result is posted. If we record the start date for a game when the game ends, then the rankings will jump around for everyone. If you record it as the resignation date, then only the ratings for the 2 players will change. If I’m understanding this correctly, then I really think we should continue recording the game end date.
HOWEVER!
You convinced me with the mass forfeits.
So the order of calling benefitted the first callers over the last callers
Of course. Because each game result recorded is a loss. Chalk it up to the uniqueness of our game (you don’t resign 10 tennis matches at once). The ELO system is designed for sequential game results, not simultaneous. Right?
HOWEVER HOWEVER
As you can see, the differences in points are marginal at best! We arrived at a point in the discussion, where we are trying to tweak the absolute nuances. Counting at beginning or end won’t shake up the rankings, nor will it lead to any substantial rating changes.
This.
My nod goes to counting at the beginning, if that’s also fine with @gamerman01 and some others.
Please let me know what you think after considering my 2 points above.
One last note
I enjoy the eagerness of everybody to find loopholes in the system and to close any doors that some might try to exploit.
:)
You WILL end up exactly where your skill level is eventually, there is no way around that.
You can run but you can’t hide. And most of us can’t quit playing.
