We can't put absolutes when we don't know the facts, all we have for most of these are rugh estimates.

The Six Great Gods are still heavily debated on thier exact level, and a world class item is not enough to point them to lvl 100, we could assume that world class items were around from the beggining of the game and that the level cap was lower then 100 so it's fair to name them at around lvl80, it could be lower or higher, we don't know untill the author confirmes it.

And that goes the same for Evil Deities, we don't know exactly who or what they were, NPCs, random monsters from YGGDRASIL, could be anywere from lvl 35-85.
