This is a list of percents where Robin's Down-throw to Up-tilt combo is a true combo on each character. To find these, I went into training mode, and took the range of percents where the sidebar registered Dthrow to Utilt as a 2-hit combo. This data should work for both the Wii U and 3DS versions of the game.

I do not have data for Mewtwo, Roy, or Ryu because I don't have their DLC yet. I also don't have data for Shulk's Mondado arts yet; that's coming later tonight.

For some characters, this never true combos. To save you the trouble, these characters are Jigglypuff, Kirby, Lucas, Rosalina*, Samus, and Villager. This happens because these characters are so light that they easily fall out of the combo. In addition, Peach, Toon Link, and Yoshi have a very small window (less than 5 between highest and lowest percent) where this true combos.
