  It is fundamental that the phase of an elastic scattering amplitude is
related to its energy variation. We repeat a previous fit to proton-proton and
proton-antiproton elastic scattering data from 13 to 13000 GeV, taking better
account of the very high accuracy of the 13 TeV data. The conclusion remains
that there is no evidence for the existence of an odderon in the small-t data
