The maximum centre-of-mass energy of the FCC-ee is yet unknown. It was inferred in Ref.~\cite{Bicer_2014} that, if the RF gradient were multiplied by three with respect to the baseline, a centre-of-mass energy of 500\,GeV could be reached, and an integrated luminosity of $500\, {\rm fb}^{-1}$ could be delivered over a period of three years, as displayed in Fig.~\ref{fig:lumi} with the red dashed line. In the framework of the FCC, the interest of such an upgrade could not be demonstrated for the physics of the Higgs boson, but it is interesting to re-evaluate this statement for in view of  the physics of the top-quark. The centre-of-mass energy was therefore varied from 350 to 500\,GeV, and the corresponding integrated luminosity was varied linearly from 2.6 to 0.5\,${\rm ab}^{-1}$. The expected uncertainties on the top electroweak form factors, $\delta F_{1V}^\gamma$, $\delta F_{1V}^Z$, $\delta F_{1A}^Z$, $\delta F_{2V}^\gamma$ and $\delta F_{2V}^Z$, were determined as explained in Section~\ref{sec:optimal}, correcting for the event selection efficiency and the detector acceptance at the beginning of Section~\ref{sec:sensitivities}, for each centre-of-mass energy. The variation of these uncertainties with $\sqrt{s}$ is shown in Fig.~\ref{fig:variation}.
