Based on the Coulomb effect hypothesis it is shown that positive even-odd effects of the maximal total kinetic energy (Kmax) and negative even-odd effects of the total minimal excitation energy (Xmax), as a function of charge (Z) and neutron number (A) of fragments, respectively, are not in contradiction. According to the Coulomb effect hypothesis, Kmax is equal to the maximal Coulomb interaction energy (Cmax) reached by the most compact scission configuration. The fragmentation corresponding to Z = 41 and A = 103 is an exceptional case for which scission configuration is formed by complementary fragments in their corresponding ground states. However, more symmetrical o more asymmetrical fragmentations than that need to be out of their ground states, which implies that Kmax = Cmax < Q.
