Recently published data on the Sachs electric form factor by the PRad collaboration (2019) [11] are analyzed to investigate their consistency with the known proton charge radius from muonic and electronic hydrogen spectroscopy, as well as theoretical predictions from dispersively improved chiral perturbation theory. It is shown that the latter is fully consistent with the data, and pointers are given how future e - p scattering experiments can lead to an improvement of our knowledge of the form factor in the low-momentum-transfer regime.
