And yet, when somebody did a giveaway of ovre 520 eggs, mine still didn't come up once. Was just the same group of numbers across all the eggs.
I still say some SVs are much rarer than others because Nintendo did that in the past with shiny pokemon. I never found one in the past because my trainer name/ID combo generated an extremely rare number for pokemon to randomly generate. Result? I've never encountered wild shinies until 6th gen fishing method. It was a total fluke that I even managed to breed out a shiny fennekin after 12 eggs[note: I haven't had another successful breeding since{and yes, I use the mesuda method when breeding}]
