You lose points for every attack that isn't a combo, even a killing blow - including the boss.
YMMV but I've found that room clear speed doesn't effect it at all, unless you get extra bonus experience seperate from the rank.
TLDR: Make sure all your hits are at least a 2-combo, even on the boss, and you'll get SSS. It's tougher then it sounds though.
