I can't comment since I don't have much experience on fragging things. All I have noticed is that once a frag grows into a colony it picks up its growth rate. At least in our tank. We don't frag stuff much unless it gets to big, but I noticed its more worthwhile to let our colonies grow bigger. Cutting into frags just slows our polyps down from what I see. I do not see the frags out growing the colonies no matter how I stack them.
I have not noticed anything dying when it gets to a certain size either, I think that would have to be related to tank issues.
I believe broadcast feedings is what helps our tanks. We over feed for sure but keep parameters in check at the same time. No need to target feed since we are doing this.
