Is the basic algorithm for assigning ratings known? I'm not looking for the exact details, but I'd like to understand things like:
• Is a difference of X points supposed to represents a probability of winning games, like ELO ratings?
• How sensitive is it? As you play more games, does it get harder to move your score due to averaging, or does it eventually "forget about" old game?
• Presumably it moves more quickly if you win against a stronger opponent or lose against a weaker opponent?
• What is the range of the ratings?
Interested in whatever can be shared on this. Thanks.
