Blue: my provisional ECF rating. Gray: confidence interval calculated in the following fashion. The upper (resp. lower) bound correspond to all remaining games being wins (resp. losses) against the typical good (resp. weak) opponent. The typical good (resp. weak) opponent has ECF rating equal to the average ECF rating in my team's division plus (resp. minus) one standard deviation. For games 0 to 5, my team's league was the Leeds League Division III (good: 1541; weak: 1140) while, for games 6 to 10, it was the Leeds League Division II statistics (good: 1704; weak: 1477). The titles indicated by the colored rating bands are the titles of the English Chess Federation while the percentiles indicated on the right derive from a post of the Yorkshire Chess News regarding the ECF rating list of 1 August 2023.
