It was a geometric scale ....
Message:It didn't have the option to be a 2.5 for example so you had to be a 2 or a 3.
There was a DC version but it was intentionally a different scale to prevent the obvious comparison.
I like the 8 point scale because then one could use a die to represent an NPC.
Sometimes, it's better to not know.
I prefer to use the standard of who was created first ... Supes beats Batz because he was around first ... just how the rulez works. Don't try to do the physics, the writers can do as they please.
