What level is the Ditto and what is its Special Defense?
make sure you set the nature right on the calculator because that will play around with numbers.
Are you sure it's Scatters Things Often? Because if you put in Often Scatters Things (and there is a difference), the IVs come out fine as
Ditto - #132 (Quirky)
HP: 27
Att: 19 - 21
Def: 15 - 16
SpA: 13 - 14
SpD: 19 - 21
Speed: 4 - 6
I have the IV range
HP:26-27
Atk: 19-21
Def:15-16
SpA.: 13-14
SpD.: 19-21
