Portisch's expected score is summed for each of his matches, which gave a total expected score of 9.66. Then the formula is: new rating = old rating + (K × (W−W e)) K is 10; W is the actual match/tournament score; W e is the expected score. Portisch's new rating [14] is 2635 + 10×(10.5−9.66) = 2643.4.
Regardless of the absolute performance of the students, the best score in the group receives a top grade and the worst score receives a failing grade. Numerical values in America are applied to grades as shown below: A = 4; B = 3; C = 2; D = 1; This allows grades to be easily averaged.
The only score in which all methods give exactly the same result is an even score against opponents with no skew away from their average rating, in which case the performance rating is the average of the opponents' ratings. There are larger discrepancies closer to zero scores or perfect scores, or a larger variance in the individual ratings (in ...
It then follows that for each 400 rating points of advantage over the opponent, the expected score is magnified ten times in comparison to the opponent's expected score.

Two other charts included in Goldman's outlook show how the Magnificent Seven have outperformed the other 493 stocks in key metrics that typically drive stock performance.
Then, the raw score is converted to a scaled score. As with the other tests, a scaled score of 2100 meets the standard and 2400 is a commended performance. In 2007, the 11th grade "met standard" level was a raw score of 42, 10th was 44, and 9th was 28; 7th "met standard" with 26 points and 4th with 20. [10]
There is an expected point score determined for each band of children, and the school is then ranked based on how their pupils' Attainment 8 compares with the expected score. [ 1 ] Progress 8 scores will result in a school being placed into a banded category: well above average, above average, average, below average and well below average .
