I think the reason why there's more successful sways with purchased plans is because atomic customizes it for YOU and what she thinks will work for you personally. Also, it helps to narrow the focus on what has been shown to get good results and what hasn't. I think it's just a timesaver because it keeps you from worrying about tactics that don't even work or impede conception to the point of not being able to get pregnant at all. Just my two cents on that. :)
