Prospects for a new team in Division 4 of the London Chess League

div4tab1

The table above shows results from the 2018/19 season of Division 4 of the London Chess League in terms of the final position of the various teams, the percentage of possible game points they achieved, the mean grade of the sides they fielded and the mean grade of the teams they faced.  We can see that the position followed the strength (mean grade) of the teams very closely and there was no significant difference in the strength of the opposition that different teams faced.

We can also consider the relationship between grading and percentage of possible game points achieved, as below.

On this basis, using the equation of the fitted trend line, we can estimate what average grading would be required to achieve various points percentages:

We do not believe that relegation operates from Division 4, but team members would hardly enjoy losing all the time, so we presume that a new team would wish to average at least 40% of game points, requiring an average grade of 113.  Or an average grade of 125 would be required for 50% performance.

We now consider the possible requirements for the specific boards, using the opposition faced by Team 9 (which scored 46%).

So we see that someone playing on Board 4 would meet opposition with a mean grade around 130 and should be of a strength to have a meaningful game with opposition graded between about 100 and about 150.  (Some figures in red italics are affected by the presence of defaults.)
