In this study, the option “shortcut pairwise comparison”
was used, which is integrated in CDP. This is an
approximation to the full pairwise comparison that
omits some comparisons. The shortcut pairwise comparison
is based on the assumption that if A is (x)times
better than B and B is (y) times better than C, then A is
(x*y) times better than C. The comparison of A to C is
therefore not required
