hmm? it was to my understanding that the items wouldn't work 100% of the time, only encourage that iv to be chosen :o
but if this is true, then this is news to me! yay :)
as for Q #2, i mean like..
Let's say 2 pokemon both have perfect Speed, mk? And i really want that IV passed to the egg. If i give both parents a Power Anklet, is it now even more likely the baby will inherit the perfect speed iv from it's parents, or is that probability the same if only 1 parent has the anklet? (bottom line: does giving the same iv item to both parents help the odds of the baby getting that iv as opposed to only one of the parents holding the iv item?)
