- I think most of the problems that you may see are due to insufficient
- results. IE, not enough games. As I've played more games under the
- rating thing, the reaction of the numbers has become quite predictable
- based on the outcome. My only question would be this: I am 19k. Say
- I play a 23k even (he does not want h-cap). I am beating 23k by 40+,
- and he resigns (as he should). After such a game, I've had my rating become
- more :) negative. I'm not sure what the resolution might be, but
- a resign win over someone 4 stones weaker (even game), should not be
- the same as a 5 pt win over someone 4 stones weaker (even game). The second
- case is something that should affect your rating negatively, and the
- opponents positively. The first, it isn't clear (to me)..

- Look, I can understand if you have questions about the algorithm, and
- its fine that you bring them up. But, in using words like "suspicious",
- and phrases like 'hide that the algorithm is wrong' it sounds like you
- are accusing the IGS administrators of something. What POSSIBLE reason
- would any of these fine people have to hide anything or to do you wrong?
-
- They are providing a service at great expense (of time and effort at least)
- which it seems folks should be grateful for, or at least not accuse them
- of "hiding" things or acting "suspiciously".
-
- I will say that if I've misinterpreted your post, I apologize.
