What elo is required for each rank on OGS?

[Chritical]

I’ve been curious as to what elo is needed to reach each rank.

From observing it on my own profile, the cutoff for 2kyu is 1760; that is, 1759 → 3kyu, 1760 → 2kyu.

I was wondering if these values are standardised, and if so, what are they?

It could be that they are arbitrary and change, but I don’t know.

Any discussion would be appreciated!

I believe Glicko2 is used instead of elo. This is a post from when Glicko 2 was implemented here:

@anoek

The Glicko-2 system has several parameters that can be adjusted: the initial rating, initial deviation, initial volatility, the number of games considered at one time, and frequency of deviation updates due to player inactivity. The suggested defaults by Glicko-2 are an initial rating of 1500, an initial deviation of 350, an initial volatility of 0.06, and to process games in batches of around 10-15.

We explored a lot of different values trying to optimize the system for our purposes, and especially when group sizes of 1 were used, there were several different choices for initial deviation that produced marginally better results. However, when using group sizes of 10-15, just as Prof. Glickman recommends, the other recommended settings were pretty much optimal. As such, our implementation just uses the defaults as laid out by Prof. Glickman, because they’re great.

There have been some adjustments over the years, such as here:

2021 Rating and rank adjustments

tl;dr - Expect a notable bump in your rank. The lower the rank you are, the larger the increase. This transition is planned to take effect around 2021-01-28T01:30:00Z (UTC) . Summary of the update: We are attempting to align our low dan ranks to be comparable to the EGF and AGA low dan ranks. Currently we are projecting that a 1d OGS rank will be about .7 stones weaker than an EGF 1d and about 0.8 stones stronger than an AGA 1d. These numbers will be re-evaluated once the dust settles, but…

I’m not aware of any table comparing kyu ranks to Glicko2 here (could be wrong).

Great graph, thanks! That answers my question perfectly.

What an odd choice of font!

Aji’s Quest—The Book

Oy, I can hardly express my joy Remember this? Now Colette Bezio’s beautiful comic story “Aji’s Quest” has finally arrived IN PRINT, released by Board N’ Stones (and soon will also be available in German).

After all, he wants to become 27th Dan as soon as possible. Along the way, he experiences bizarre adventures…
