Don't Understand Grading Calculation
Posted: Mon Oct 07, 2019 12:54 pm
Last season we had a foreign student join our club with a FIDE rating that equated to about 115. Playing quick games against him we decided that he was probably a bit stronger than that and placed him in our teams based on our estimates. At the end of the season his results were 8 wins against opponents with the following grades - 132, 129, 121, 118, 125, 128, 144, 107. That looks to me to be an average grade of 125.5 which I would have thought would have resulted in a grade of 176. Instead his grade is 187. What aspect of the calculation have I failed to understand?
BTW, I did warn him that he would have an inflated grade with all wins but he went away over the summer rather than play congresses where he would have faced stronger opposition. Although we moved him up during the course of the season we were constrained by league grading difference limits and by the end of the season were perhaps exceeding them but not by enough for any other teams to lodge an official complaint.
