I'm wondering about Destiny Knot's outside-of-battle effects. Bulbapedia says says there's a "chance" for 5 random IVs to be inherited by the offspring. Serebii says it's definite. Other sources I've seen says it's a chance that 3 or 5 (not 4) IVs get inherited by the offspring. What's /vp/ verdict?

I know multiple instances where the info on Bulbapedia and Serebii is different (most of which is incorrect on Bulbapedia's side), but I'm not the person to bother fixing it as I don't have editing privileges and also think someone else might do it
