What it is
There are two reasons, and thus two ways, to count the number of hits done.
- Some moves have multiple attack hitboxes (especially strike hitboxes), or even multiple hits attached to a single hitbox, so one can count the total number of hit attempts a move has (and not all of them have to work; in fact, sometimes they never can all work).
- When one does a sequence of hits, particularly in a combo, there is a certain number of hits the sequence does.
