I've never gotten this or bothered to understand since I started, but now I'm actually caring due to actually playing with thought.

When a skill says "Hits X times for Y%" does that mean it does:
A) X * Y% damage, with Y% represents the damage of a single hit
B) Y% damage over X hits and thus (Y% / X) gives % damage per hit

For example: "Deals 6 very quick consecutive attacks to a monster - Level 20: MP -26, Damage: 90%"
So does this mean it does
A) 6 * 90% and each hit is 90%?
or
B) 90% / 6 = 15% damage each hit?

I get the feeling if I cared more about math I'd not need to post this question.
