Let's say that I kill 200 goldeen to get all the Attack evs i need. But, my poke only leveled up to 50. Will it still get the preferred attack stat at lv 100 if I stop killing those goldeens. If it's complicated to answer I'll rewrite the question more clear on my computer later.
Once you max out ur attack evs then u dont need to up it. seeing as that each goldeen will give 1 attack ev, you wont max it out. But, at level hundred you will get all 50 points (200/4). it just adds up a little later, you wont get all those points instantly.
tell me if that sounds wierd, ill try rephrasing it.
