aha, yeah I've noticed that usually you kind of hit a plateau in experience gain once you clear one side of the jungle. If the other side doesn't have a jungler, you can go clear that side and possibly keep the same pace, but if they do have their own jungler once you hit 4 or 4.5/5 you get to play the waiting game (waiting for jungle to respawn or waiting for gank in brush).
