Beckett Final Grade and GPA Calculation
(These are mostly things I've observed personally - not official information released by Beckett, although some things I was told by Beckett reps)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Final Grades (For purposes of this post, I will list subgrades in order of - Centering, Corners, Edges, Surface):

1. The final grade is not an average.

2. Generally, the minimum subgrades that are required to achieve a certain final grade is 3 subgrades at the final grade and 1 subgrade at 0.5 below the final grade - there are exceptions to this rule (explained later).
Examples:
3x9.5 and 1x9 is the minimum requirement for a final grade of 9.5.
3x9 and 1x8.5 is the minimum requirement for a final grade of 9.0.

2. If the lowest subgrade occurs twice, then the lowest subgrade is the final grade.
Examples:
9.5 9.5 8.5 8.5 will have a final grade of 8.5.
9.0 6.0 4.5 4.5 will have a final grade of 4.5.

3. Usually, the final grade cannot be more than 0.5 points above the lowest subgrade if several of the other subgrades are close to the lowest subgrade.
Examples:
8.5 9.5 9 9 will have a final grade 9.0
4.5 5 5.5 10 will have a final grade of 5.0

4. Some subgrades are valued higher than others. Beckett values them in order of Centering, Corners, Edges, and then Surface.
This ordering is the reason we see what some people may consider discrepancies in final grades.
When 3 subgrades are far above the lowest subgrade, then the final grade can be more than 0.5 above the lowest subgrade; however, how much the other 3 subgrades need to be above the lowest subgrade to net a final grade that is 1.0 above the lowest subgrade varies based on which subgrade is the lowest.
It is much easier to get a final grade that is 1.0 above the lowest subgrade if the lowest subgrade is edges or surface because those 2 are valued less by Beckett. See picture of the Nevinyrral's Disk - 9.5 9.5 9.5 8 nets 9.0.
It is harder to get a final grade that is 1.0 above the lowest subgrade if the lowest subgrade is centering or corners. This is because Beckett values those 2 more. See scan of the Shivan Dragon - 8 9.5 10 9.5 nets 8.5 even though the simple average is higher than the simple average of the Nevinyrral's Disk.
In rare cases if 3 subgrades are far far above the lowest subgrade when the lowest subgrade is centering or corners, then it is possible to achieve a final grade that is 1.0 above the lowest subgrade. See scan of the Counterspell - 7 9.5 9.5 9.5 nets 8.0.
When the lowest subgrade is extremely low (in the 1.0-4.0 range), then the final grade can be more than 1.0 above the lowest subgrade if all other 3 subgrades are extremely high. See grading summary of the Library of Alexandria.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
GPA (For people with registries) - The GPA calculation is Beckett's way of showing that a card with a certain final grade can be superior to another card with the same final grade:

1. Most of the time, a card with a subgrade that is 0.5 below the final grade has a GPA that is the same as the final grade.
Examples:
9 9 8.5 9 has a final grade of 9.0 and has a GPA of 9.00.
9.5 9 9.5 8.5 has a final grade of 9.0 and has a GPA of 9.00.

2. If all the subgrades are at least as high as the final grade, then the GPA is 0.1 above the final grade.
Examples:
9 9 9 9 has a final grade of 9.0 but has a GPA of 9.10.
9.5 9.5 9.5 10 has a final grade of 9.5 but has a GPA of 9.60.

3. If all the subgrades are at least as high as the final grade and the card is 0.5 of a subgrade away from the next final grade, then the GPA is 0.15 above the final grade.
Examples:
9 9 9.5 9.5 has a final grade of 9.0 but has a GPA of 9.15.
10 10 9.5 9.5 has a final grade of 9.5 but has a GPA of 9.65.

4. If all the subgrades are at least as high as the final grade and one of the subgrades is 1.0 or more above the final grade, then the GPA is 0.15 above the final grade.
Example:
10 9 9 9 has a final grade of 9.0 but has a GPA of 9.15.

5. If a card has 3 subgrades that are 0.5 above the final grade and 1 subgrade that is 0.5 below the final subgrade, then the GPA is the final grade if the lowest subgrade is centering or corners but the GPA is 0.15 above the final grade if the lowest grade is edges or surface.
EXamples:
8.5 9.5 9.5 9.5 has a final grade of 9.0 and has a GPA of 9.00.
9.5 9.5 9.5 8.5 has a final grade of 9.0 but has a GPA of 9.15.
10 10 10 9 has a final grade of 9.5 but has a GPA of 9.65.

6. If a card has 2 subgrades that are 0.5 above the final grade, 1 subgrade that is 1.0 or more above the final grade, and the surface subgrade is 0.5 below the final grade, then the GPA is 0.20 above the final grade.
Examples:
9.5 9 9 8.0 has a final grade of 8.5, but has a GPA of 8.70.
9.5 9.5 10 8.5 has a final grade of 9.0, but has a GPA of 9.20.
