That is not a question you should need to ask three and a half years after the game has been launched.
Also, my understanding was that stats, not IVs, have a range.
So for instance, there are 40 points between a manamon's attack stats "terribly underdeveloped" vs. "perfect". This is assuming full training, by the way. For each gradation, the stat jumps by like 5-7 points or whatever it is. So "not so good" would be 5-7 points better than "terribly underdeveloped", and so on.
I could be wrong on this, of course.
And as I say, perfect should be perfect regardless. Perfect should not be a range.
