Street Fighter V handles chip damage quite differently from previous Street Fighter games. The fact that medium and heavy normals deal recoverable chip damage, but only Critical Arts can actually secure a kill against a blocking opponent means that ending a round through such methods takes a good deal more planning than just hoping someone blocks one too many fireballs.
In this new video, SFtheWolf demonstrates some optimal chip damage setups that characters can use to try to close out matches on a blocking opponent.
The setups below are designed not just to deal as much chip damage as possible, but are also true blockstrings, meaning that the opponent cannot reversal out of them except with a V-Reversal. Take note, however, that the damage values shown do not take into consideration the guts-style damage scaling that takes place at the end of a health bar, so the numbers presented will be slightly reduced when these tactics are attempted to close out a match.
