just curious because on one of mine the subs were
If I add those up and divide by 4 I get 9.125 but the overall grade was 8.5 instead of 9.
Am I missing something or is there more to calculating the overall grade ?

For example, if a given set has a lot of cards that are often off center, does centering weigh more (because it is a significant/obvious characteristic of the set) or less (because it is a typical characteristic)?
And does that go for individual cards also? Say a certain card often has a specific print spot on the surface; Do they weigh surface subgrade less because of that?
