We demonstrate that the electron-phonon coupling calculations performed using the ${\\sigma}$-broadening of the double ${\\delta}$-function at the Fermi surface lead to a very strong dependence of $\\textit{T$_c$}({\\sigma})$ on the arbitrary ${\\sigma}$, whereas the tetrahedral method for the electron-phonon interaction is free from this drawback and leads to $\\textit{T$_c$}$ > 300 K at 300 GPa in agreement with previous predictions.
