Andrew didn’t play any rated game on that acount for 7 years and Sandy only played 6 rated games on that account in the past 7 years. So those two may not be the best examples.
After the coming EGD update, Matt’s EGF rating will have fluctuated around 2k in the last 3 years. His new OGS rating has fluctuated around 1k OGS in that same period.
After the coming EGD update, Gerry’s EGF rating will have fluctuated around 10k for the last 4 years. His new OGS rating has fluctuated around 6k in that same period.
Here is a different case where is used some estimate from play quality:
From this small number of anecdotal cases, the following rough comparison table between new EGF ranks and new OGS ranks can be made:
OGS EGF
--- ---
1k 2k
4k ~6k
~5k 9k
6k 10k
7k ~10k
9k ~15k
This may seem “wrong” for players who are used to EGF ranks, but a similar comparison table between new OGS ranks and AGA ranks may show a different picture.
I think that the data acquired from the recent rank linking feature was used to fit the new OGS ranks somewhere between EGF ranks and AGA ranks.
