  The charge radius of the proton is typically determined from electron-proton
scattering by extracting the proton's electric form factor and then making use
of the derivative of that form factor at zero four-momentum transfer.
Unfortunately, experimentally, one cannot measure to zero four-momentum
transfer and thus extrapolation is often required. In the work of Alexander
Gramolin and Rebecca Russell, they present a novel method that does not use the
slope and found a radius of the proton that contradicts many other recent
results. Our analysis of their paper discusses some issues with this method and
we show that by simply changing the binning of the data and/or including an
additional set of data the results change dramatically.
