I appreciate this greatly. Prior to this video I thought -7 could be punished with 6T (with non-grappler) but such is not the case. Now I know that I can punish everything which -8 or worse. Also I didn't know that Hayabusa is a grappler :O
Throw punishment is how you punish unsafe attacks or strings in Dead or Alive.
How throw punishment works in Dead or Alive is that you need 1 frame to execute your throw for punishment.
Example: To use a 5 frame neutral throw for punishment you will need the attack or string to be at least -6 on block. If the attack or string is -5 on block you will not be able to use a 5 frame throw to punish it.
Refer to that example whenever you want to use certain throws to punish attacks or strings that leave a character at disadvantages where a throw can be used for punishment.
