  An asymptotic scaling law for drag in flat-plate turbulent boundary layers
has been proposed [Dixit SA, Gupta A, Choudhary H, Singh AK and Prabhakaran T.
Asymptotic scaling of drag in flat-plate turbulent boundary layers. Phys.
Fluids Vol. 32, 041702 (2020)]. In this paper we suggest to amend the scaling
law by using a correction term derived from the logarithmic law for the mean
velocity in the streamwise direction.
