[Computer-go] zen19n

[Brian Sheppard]

So in the 2d+ ranks, each rank wins ~80% against the rank below.

For KGS ranks:

2d+ each rank is 226 Elo (k=1.3)

5k- each rank is 139 Elo (k=0.8)

Between there is some sort of sliding scale.

Can anyone tell me how wide a KGS rank is in Elo units?

 

E.g., how often will an 8d beat a 7d if they are exactly 1 rank apart?

 

Thanks,

Brian

Zen19N has always used 20+5x:30, so the time settings are no different.  The
rating graph spike in December to 5d is probably just drift -- it quit
playing in November.  But when it was playing it was holding a solid 4d
rating.

I think it has a lot to do with the long time settings. Reduction about
150 to 250 Elo in strength seems roughly consistent with our experience
with Pachi.
