First, arrange the data in order of declining accumulation rates, so that the "first" period has the highest rate and the "last" has the lowest. This imposes the largest possible negative second derivative on the data. Second, reverse the order (so that the one with the lowest rate is first). This imposes the largest possible positive second derivative on the data. The results are, in the first case, an exponent of 0.866 in a power fit, and in the second, an exponent of 1.204. The figure shows the polynomial approximations of these curves.
