While there is unanimous agreement that all $g-2\mathrm{}$ data are in excellent agreement with special relativity, some statements made in the discussion need clarification. There is no viable "Newtonian" interpretation of the basic $g-2\mathrm{}$ formula. Also, distinguishing between different kinematical $\gamma$'s implies a model afflicted with logical inconsistencies. On the other hand, a logical post-Einsteinian alternative to special relativity could conceivably involve a breakdown of the special-relativity momentum-velocity relation, tested by comparison of the kinematical $\gamma ={(1-\frac{v^2}{c^2})}^{-\frac{1}{2}}$ with the dynamical ${\gamma }_M=\left(\frac{p}{m_0}\right)\left(\frac{\mathrm{dp}}{\mathrm{dE}}\right)$. The $g-2\mathrm{}$ experiments have as a by-product confirmed the consistency and applicability of classical special relativity over a very wide range of velocities but at relatively small accelerations.
