AGS3 - player's AGS3 grade for 2011 season
GSLAST09 - player's GS grade for 2008 season
AGS3LAST09 - player's AGS3 grade for 2008 season
GS-GSLAST09 - player's GS grade improvement in 2011 season since 2008 season
AGS3-AGS3LAST09 - player's AGS3 grade improvement in 2011 season since 2008 season
GS grade - official ECF current Grading System grade
AGS3 grade - ECF Amended Grading System three grade
(player's AGS3 grade for 2008 season was taken to be the same as player's GS grade for 2008 season)
Grading anomalies...
Example: Since 2008, according to GS, the grades of 273626D John Paul J Taylor and 121043K Steve Walls drifted apart for 119 grading points, but according to AGS3 they should have drifted apart for about 87.97 grading points. The question is is the 87.97 a better guess than the 119? (It is obvious that GS stretches the grades in respect to AGS3. If it has been found that the GS grades were stretched, if the stretching is inherent in the GS calculation method, the problem could be resolved by correcting the calculation method by say applying AGS3 or better ÉGS6.)
