I haven't thought this through much, but assuming clients are connecting to instances at "random", then isn't the probability of a instance requring a block for which it is already the holder approx 1/n, where n is the number of the nodes. So as the node count rises, you'd get a reduced likelihood of "success" ? I suppose dynamic remastering is meant to assist with this as well.
