First option is clean SDG, I don't really have clean scores nor do I see clean SDGs that often because I'm playing high FGOs, but yeah I don't really call that a SDG

Second option... well it's the literal term, SINGLE digit good.

Third option is the one I picked, because as long as your raw score is higher than (AAA-250), it's considered SDG imo.
