That is one of the outstanding problems of the ISTI benchmark: how jumpy or how gradual are gradual inhomogeneities such as the ones caused by urbanization.<br /><br />It is a pity that they did not plot the difference time series. Then you would have been able to see such changes and jumps more clearly.
