I regularly frag from the center of my colonies by adding a small peice of rubble to the center and just letting it sit, I then go in about three weeks later and just cut the rubble out. I have tried both fragging form the edge and the center and beleive that the center frags faster, of course me method of fragging is a little different being that I do not cut the frag and glue it but let it grow onto the rubble naturaly! also I have noticed that my frags at the bottom of the tank deff grow slower and that is not only due to lower lighting but the fact that the flow is much lower at the sand level in my tank! just thought id share!
