They are calculated by a complex algorithm. That is described on the ratings page. There is no strict line between provisional ratings and regular ratings. The same algorithm is used to calculate all ratings. You can consult the number of games played by each player as a guide to the trustworthiness of the ratings. Ratings are meaningful only relative to each other. Your suggestions about using computer players to set standards for what the ratings mean could not be implemented without destroying what the ratings already mean. Besides that, it would be wholly impractical, given the large number of games available here, and given that Zillions of Games, the only software available for playing most of the games here, does not let users set ply levels.
