See, I have a question about the evs. I use the Super Training to EV train my pokemon, and there's no way to tell if I reached a certain number in the stat. So how would I know if I reached 168 Speed?
Get a counter, or see if theres one online, and just add 1 every time you add an EV.
This is why EV training was so easy in D/P/Pt, the bottom screen had a counter app to easily keep track of your progress.
