This work suggests that the exponent of (Formula presented) found in Ref. 18 for a point-island model with 1D diffusion is shifted to (Formula presented) for islands of finite extent. This is not observed in our model, or in new benchmark studies of a square-island model [M. C. Bartelt and J. W. Evans (unpublished)].
