I think you've confused IVs, PVs and EVs. Just to be clear:
IVs = Individual Values, numbers for each stat ranging from 0 to 31 that are equivalent to 1 stat point at level 100.
PVs = Personality Values, which are extremely complex integer codes that determine Shiny Pokemon, among other things.
EVs = Effort Values, points Pokemon gain in their stats for beating Pokemon. At level 100, 4 EVs = 1 stat point. A Pokemon can have a maximum of 510 EVs and a maximum of 252 in one stat.
