 Finally again with the same accuracy formula_118 is changed for "x""p" under the summation sign and thus represent τ"s" as

The variance of this sum in the limit of large "s" is

 depend only on the differences |"p" − "p"′|.The mean value formula_119; the mean square

formula_120

By taking into account also the values of correlations formula_121 with "p" = 1, 2, 3
(calculated numerically) the final result "D"τ"s" = (3.5 ± 0.1)"s" is obtained.At increasing "s" the relative fluctuation formula_122

The respective statistical distribution is given by the same Gaussian distribution in which the random variable is now "s"τ at a given τ
