  A detailed analysis of the existence of high energy secondary diffractive
dips and structures in the extrapolations of the fits to the data is given. The
existence of these dips and a fortiori their position is found to be rather
model-dependent: present in all eikonalized models including Pomeron, Odderon
and secondary Reggeons they disappear when an additional large- t term is added
(as sometimes advocated).
