Comment on "Intermittency exponent of the turbulent energy cascade".
It is argued that the method used by Cleve et al. [Phys. Rev. E 69, 066316 (2004)], to determine the intermittency exponent mu is biased at moderate Reynolds numbers R lambda. Thus, the claimed dependence of mu upon (R lambda) is questionable. Other determinations give a constant value for mu.
