First of all, I'm not sure if it's the right place to post that question. Let me know, and I'll post somewhere else. With that being said, let's get to my question. So, 31 IV is obviously better than 0. This is not where I want to aim the conversation. I'd like to talk about perfect IV vs almost-perfect IV (25-30). Of course, having an IV at 31 is better than having it at 25-30. However, I'd like to know if that little difference will be significant in the end. I'm asking that because I now have 2 Dittos for breeding and they both have 4 perfect IVs and a 5th almost-perfect, and I'd like to know if it's worth using them, or if I should aim for 5 perfect IVs. My physical breeding Ditto: HP:31 Atk:31 Def:31 SpAtk:irrelevent SpDef:26 Speed:31 My special breeding Ditto: HP:31 Atk:Irrelevent Def:31 SpAtk:25 SpDef:31 Speed:31 So, does having IVs at 25-26 will make a significant difference in the end?
