I'm sure rank changes for anchors are only slightly smaller than for normal players. The way one would implement anchors is by fixing their average rank. If there are 20 anchored players the rank of each of them should change only about 5% less than it normally would(and it would pull the whole world with him by that amount).

It's even possible to automatically add and remove anchors. If an anchor moves too much relative to the other anchors he gets dropped and somebody more consistent gets added in his stead. IMO good anchors are slowly improving players who play many games. I assume most how satisfy that criterion are mid dan level players(thecaptain comes to my mind). Bots with a fixed implementation could be a good idea as anchors too.

they are anchors because their rank is steady

their ranks are not steady because they are anchors

What if an anchor jumps a stone or two (For example, he/she takes 3 months and devotes them to the game), would it be at all possible for the anchor to move ranks?

This could be the criterion by which someone becomes an anchor (their rank appears steady), but as anchors are a basis for the rating system, I do not see how their rank could not be calculated differently than a normal user.

As I understand it, anchor ranks can move, just much more slowly than "normal" ranks. If an anchor really did have a dramatic change in strength I would imagine they would be removed as an anchor (Alternatively, everyone else on the server would have to study hard to maintain rank (= ....darwinian rankings ).

winning 15/16 won't make you a good anchor, it means you're under-ranked or on a roll.

winning 9/16 or 8/16 might be a good choice for anchor...

Their ranks are not calculated any differently. Its just that their ranks don't usually change much. That's why they were chosen as an anchor.

I think it is hard to compare. Tartrate was 9 dan who defeated pros and 9 dan (We miss you Tartrate).

Strictly speaking, Tartrate was [7d?] the 9 dan ranking on KGS wasn't added until later that year (=

I think it's been established that the average rank of all the anchors is what is "anchored," not the rank of each individual anchor. "Someone whose rank is changing quickly can't be an anchor" is a teleological explanation, not an efficient explanation.

I don´t remember if Tartrate was 7 or 9, i just assumed he was 9. I remember all those games with LOTS of people watching.

Myungwan wrote on his senseis' page that he'd beaten mymy on KGS, from which it was inferred that he was Tartrate--I guess very few people managed to beat mymy.

before Joanne Missingham aka Hei Jia Jia became a pro,
she asked her mom to take her to China pro exam if she can achieve 9d on the internet
she didn't say which server but i guess it's KGS

The server was YiCheng (Chinese edition of Tygem), She usually played in the Korean Room 1.
Interview in Chinese: http://sports.sina.com.cn/go/2008-04-02 ... 1613.shtml

There are tons of 9d amateur players in Tygem. To pass the pro exam, for a girl 9d is strong enough, but for a boy he has to be a very strong 9d.
