Abstract
Shortcomings of the new zero trajectories of H\"ohler and Sabba Stefanescu are pointed out. The errors in the imaginary part could be large enough to make their results consistent with at least one real zero for every energy. Whether or not a real zero exists, it is possible to have convergent polynomial expansion (CPE) without any spurious cut with (very nearly) the same ansatz for the forward slope. We disagree with most of the criticisms on the applications of CPE to scaling without any spurious cuts. Even if one uses slope values obtained from parametrizations in the Coulomb-nuclear interference region, scaling is described in an excellent fashion.
