Takebacker's Ultimate Brawler Guide

The wording in the description seems to imply that it does, whereas it doesn't specify like that for Corkscrew Blow or Backspin Blow. I could be horribly wrong though.

Well i would think a skill like that would add the stated percentage to each hit (if the skill hits more than once) even if it wasn't explicitly stated, but still even with 3 hit corkscrew it wasn't per hit. :/ I didn't notice much increase in DU but i'll mess with SP resets a bit when i get on.
