I made a quick plot of Elo per rank for the new rating to rank formula:
Red curve is from the new OGS conversion formula
Blue curve is from the new EGF conversion formula (to be implemented soon)
Horizontal axis is the OGS rank (0 = 30k, 30 = 1d, 42 = 13d = new max rank in EGD)
Vertical axis is the Elo width per rank.
In the range of 30k - 5k, it is quite a close match (30-70 Elo per rank).
So the new OGS formula will make OGS kyu ranks as soft/tough as EGF kyu ranks and I expect that OGS kyu ranks will align much better with EGF kyu ranks. Definitely good news!
In the high dan range, the EGF formula gets tougher than the OGS formula.
So over time, EGF mids dans may get high dan ranks on OGS.
It may turn out that OGS high dans will be comparable with high dans on asian servers.
But I’m not saying that this is a bad thing. In the past, EGF 6 dans could be 9d on KGS and I didn’t hear much complaints about that back then

Many thanks @anoek!
