Rating system
Harkness devised a rating system that was used by the US Chess Federation from 1950 to 1960. When a player competes in a tournament, the average rating of his competition is calculated. If the player scores 50% he receives the average competition rating as his performance rating. If he scores more than 50% he new rating is the competition average plus 10 points for each percentage point above 50. If he scores less than 50% his new rating is the competition average minus 10 points for each percentage point below 50 (Harkness 1967:185-88).
