  We show that the impact of the maximal odderon amplitude at t=0 and
centre-of-momentum energy 13 TeV is small. We obtain a value of rho(t=0) at 13
TeV of the order of 0.12. The real part of the odderon amplitude grows like
log(s/s0) at high energies, and is calculated from the analytic properties of
the amplitude. In the framework of the HEGS model, taking the same intercept
for the odderon and the pomeron leads to a good fit of the new LHC data at 13
TeV. We also show that the main effect of the odderon can be seen in the region
of the diffraction minimum of the differential elastic cross section. The form
and energy dependence of the odderon amplitude determined in the HEGS model
reproduce the characteristics of the diffraction minimum at 7, 8 and 13 TeV.
