Detailed / Advanced IGS rating question
Posted: Fri May 10, 2013 5:22 pm
I often start new accounts on IGS - typically when I try a new joseki or fuseki.
Sometimes, if I get off to a good start (4-1 or 7-3) IGS will automatically "promote" me. So I might go from 3d? to 4d?
My question is this - if my provisional rating (e.g. 3d?) gets promoted what's the effect to my eventual Xd* rating if I choose to override IGS and reset back to where I started. For example let's say I start at 3d? - I play 10 games and win 7 3 lose 3. At that point IGS automatically says "4d?". At this point I have a choice (I think):
1 - Stay at 4d? - probably lose a bunch of games - and maybe when I hit 20 rated games get a 2d* (I've seen this double-demotion happen)
or
2 - Manually reset back to 3d and maybe win about 50% - I know that you have to win 12 of 20 to get the * you started with.
Any ideas about how the IGS algorithm works in these cases?
Thanks
