My teams are only ever good in-game, nowhere else. Simply because I don't EV train them like most people do. Good lord. I lose constantly in anything other than in-game battles xDDD
I fail at this. xDDD
Don't worry, you'll get efficient once you get into a routine. I originally wasn't heavy on EV Training myself. Eventually I went to the point where I decided to EV Train my entire in-game team for B2W2.
Ev training is a drag ingame tbh.
I only reccemond EV Training for competitive play.
