Points for average of matches won over matches played
In addition, the percentage of matches won divided by matches played is converted to points, which is then added to the cumulative points gained each week for playing & winning. Early in the season, the points gained from the average of matches won over matches played can have a bearing on a players ranking, but as the season progresses, its effect becomes less, with the more matches that a player plays.
Hence, the ranking list favours the players who play regularly every week over the season. It is NOT meant to be an accurate representation of player ability, since it gives a significant number of points for playing.
