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) and 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 official ratings are published and used in tournaments entered.
