The four subgrades are corners, edges, surface, and centering. I think you're asking why they're not equally valued in the overall grade. It's likely because some are more important to eye appeal, based on the grading company preference based on what they think customers prefer.
When people first look at cards at arm's length, they immediately notice the centering and corners. Edges and surface (light creases, etc) are less noticeable. At high grades (like above 7), the overall grade can only be like 0.5 grade higher than the lowest subgrade.
As you move down the grading scale, you can get a grade 1-2 points higher than the lowest subgrade. It's not a straight average, because a card with a pinhole (surface of 1) could still have Gem Mint 9.5 centering, corners, and edges. But the card will likely max out at a 2.
