The post was okay, but it felt like alot of the info was coppied from the EV Hotspots Guide at gamefaqs.
Also, another good tip is the power items. Power Items give you a straight bonus of 4 EVs of that given type. Meaning the HP power item will give you 4 HP EVs if you get one HP EV from the enemy you're fighting. That 4 stays constant per enemy. This is also still doubled by PKRS meaning that, using the example of cowgirl shelley, who has 5 Bidoofs (if i'm wrong, correct how many she has :0P )gives you 50 HP EVs per battle, meaning you only have to fight her 5 times, then make your poke beat on a single, lonely bidoof somewhere else.
