Division 9.2.1.3 The distances of the extra high speed phase of the base cycle dbase,exhigh and the interim capped speed cycle dcap,exhigh shall be calculated applying the following equation to the extra high speed phase of both cycles:

d_{exhigh} = \sum (\frac{(v_{i} + v_{i - 1})}{2 \times 3,6} \times (t_{i} - t_{i - 1}), for i = 1 479 to 1 800)
