Sevenoaks League Ratings
The ratings shown are based on results played in the Sevenoaks League only. For the season 2017/2018 initial ratings were taken from the TT365 ratings at September 2017. This has corrected some anomalies in the past where estimated initial ratings have been too low. Players not having played Sevenoaks League in 2017/2018 will be allocated a provisional rating, in red, which will be adjusted during the season .
The points matrix shown below has NOT been changed and is the same as used in the Sevenoaks League for many years. This means that the winner of a set gains the same number of points as his opponent loses.
