Anyone else having problems with this? i feel like im doing it wrong but i followed people's tutorials and did everything the way they did it but it wouldnt give me the same results.

So all my pokemon have pokerus, i have my power item on my lead pokemon and i have exp share on. i go for atk, do the sos method to get them to call help and i was told 7 help kills = 252. so i do kill 7 and nope, my pokemon only got like 50 ev's in atk.

so i ask my friend how he did, EXACTLY THE SAME WAY AS I DID, KILLING 7 AND HE GOT 252 EVS. WHAT. AM. I. DOING. WRONG?
