Hey, I saw your question about EV training. Here's what happens and why you don't see any huge leaps in stats: it's because you only get all the stat points from EV training when your Pokemon is level 100. Otherwise, the amount of stat points you get for a particular stat depends on the level. Smogon's EV training guide is the best and the one I used to understand the mechanics, here it is.
