To try to understand the source of these differences, we make use of the analytically well-behaved rational (<math><mrow><mi>N</mi><mo>=</mo><mn>1</mn></mrow><mo>,</mo><mo> </mo><mrow><mi>M</mi><mo>=</mo><mn>1</mn></mrow></math>) function, a predictive function that can be reasonably used for extrapolations at <math><mrow><msup><mi>Q</mi><mn>2</mn></msup><mo>\u2192</mo><mn>0</mn></mrow></math>. First, we test how well this deceptively simple two-parameter function describes the extremely complex and state-of-the-art dispersively improved chiral effective field theory calculations. Second, we carry out a complete re-analysis of the 34 sets of electron-proton elastic scattering cross-section data of the Mainz A1 Collaboration with its unconstrained 31 normalization parameters up to <math><mrow><msup><mi>Q</mi><mn>2</mn></msup><msup><mrow><mo>=</mo><mn>0.5</mn><mspace width=\"0.16em\"></mspace><mrow><mo>(</mo><mi>GeV</mi></mrow><mo>/</mo><mi>c</mi><mo>)</mo></mrow><mn>2</mn></msup></mrow></math>. We find that subtle shifts in the normalization parameters can result in relatively large changes in the extracted physical qualities. In conclusion, we show that by simply using a well-behaved analytic function, the apparent discrepancy between recent form-factor extractions can be resolved."
