In August 2020 the ECF Rating system was changed from an historic 3 digit grading system to a 4 digit ELO type rating system.
The
fundamental change being that in the new system a player's rating is
adjusted after every match based on the relative rating to the opponent.
The calculation is the result ( 1 , 0.5 or 0) less the expected score
(from rating table) times a constant k (40 for juniors 20 for
adults).
So on winning against a player of an equal rating the
expected score is 0.5 and therefore if an adult the live rating will
increase by 10.
At the end of every month the ratings are published as an official monthly rating.
