Ok, I will try to clear things up. I didn't know that is why you lvl'd the Pokes so that is cool. But, in 4th gen, one had to lvl up a Pokemon that was trained from battling to show the EV improvements. So, many people thought they had to lvl up a Pokemon in all cases to show all EV improvements. Well, 5th gen did away with that. Now, after every battle if you got 4 total EV points in a stat it will immediately show now, you wouldn't need to lvl up for it to show...hopefully that makes more sense.
