Anticipating forthcoming publication by the TOTEM collaboration of low-[Formula: see text] elastic scattering data at [Formula: see text] = 13 and 2.76 TeV, hereby we emphasize the correlation between two prominent structures seen upon the otherwise exponential diffraction cone, namely a “break” staying fixed around [Formula: see text]0.1 GeV2 and a dip moving with energy logarithmically inwards; while at the ISR, the two structures are separated by a distance of about 1 GeV2, at the LHC, the dip comes close to the periphery of the “break”, thus affecting its parametrization. An unbiased disentangling and identification of the “break” at the LHC should account for this correlation.
