Abstract: The $Q^2$ dependence of the ratio of the cross sections with and without spin flip, as well as the polarization asymmetry in the $e \vec p \to e \vec p$ process, has been numerically analyzed using the results of JLab's polarization experiments on the measurements of the ratio of the Sachs form factors in the $\vec e p \to e \vec p$ process. The calculations have been made for the case where the initial (at rest) and final protons are fully polarized and have a common spin quantization axis, which coincides with the direction of motion of the final proton. The longitudinal polarization transfer to the proton has been calculated in the case of the partially polarized initial proton for a kinematics used in the experiment reported in [A. Liyanage, W. Armstrong, H. Kang, et al. (SANE Collaboration), Phys. Rev. C 101, 035206 (2020)], where the double spin asymmetry was measured in the $\vec e\vec p \to ep$ process. A noticeable sensitivity of the polarization transfer to the proton to the form of the $Q^2$ dependence of the ratio $\mu_pG_E/G_M$ has been found. This sensitivity may be used to conduct a new independent experiment to measure this dependence in the $e \vec p \to e \vec p$ process. A criterion to assess the reliability of measurements of the ratio of Sachs form factors using the Rosenbluth technique has been proposed and used to analyze the results of two experiments.
