Resumen The angular-averaged differential cross section (dcs) of the elastic electron proton (ep) scattering, covering Q^2 < 1.0GeV^2, was fitted via a combined modified eq-scatterings where q is a point particle. The modifications represent the cloud-covering effects to q. An energy-decaying ratio (edr) was derived by inspecting the generated dcs ep from the form factor data gathered at Mainz Microtron (A1-Collaboration) and Continuous Electron Beam Accelerator Facility (Jefferson Laboratory) when compared to the dcs eq with modified relativistic recoil factor. The diminishing cloud layer, edr, has a decay rate of -2.8 for the data sets under investigation. The formulated SBM and SEM fitting models use the bare and effective u and d-quark masses, respectively, while SCBM and SCEM integrate other considerations. Three comparison methods were used and all of them favor the models with other additional considerations. SCEM was the most favored model in general.
