For those wondering, HGA doesn't use the exact same scale as BGS.
- They allow the overall grade to be 1.0 point above the lowest subgrade (2.0 above if overall grade is lower than a 5 I believe)
- If a card has 2 lower subgrades (8.5s) but the rest of the subgrades bump the average above that subgrade (9.0), the overall grade will be the average, not lowest subgrade like BGS.
