Surrey Junior Chess Championships
My notes on grading
- After each event I submit the results for the Under 13s, Under 12s and Under 11s to the English Chess Federation for the purposes of grading. Therefore, everyone new to the ECF grading system, playing in those events will get an ECF grading code shortly following submission, no matter what their performance.
- Prior to sending the results I put the excel submission sheet through a checker program which provides me with estimated gradings for the ungraded players. These are the numbers shown in red.
- Grades with a star(*) are either taken from the previous year, or slow play grades - only used where the player doesn't currently have a rapidplay grade. I always try and find a recent grade where possible.
- The column named 'Perf' is the estimated ECF grading performance for this event, and you can view individual results, and do your own calculations by clicking on the player's name. This column is only shown for the graded events.
- Normal grading points are earned as follows:-
- For wins take the number portion of the opponent's grade and add 50 points.
- For draws take the opponent's grade.
- For losses take the opponent's grade and deduct 50 points.
- Sum up the points scored and divide by the number of games (played only).
- If the opponent is graded more than 40 points above, then they are treated as being exactly 40 points above. Which means you can't gain points by losing to someone far stronger than yourself.
- The same for those opponents graded 40 points below, they are treated as being exactly 40 points below.
- You then do the calculations as above.
