The zero field in-plane normal-state resistivity of the Ba(Fe1-xCox)As2 (x = 0.00.3) single crystal above Tc can be reproduced among other possibilities by a very simple expression and scaled thereby using the temperature independent energy scale Δ, resistivity ρΔ, and residual resistivity ρ0 as scaling parameters (E. Arushanov, et. al. Supercond. Sci. Technol., 24, 105004 (2011)). We show that this Δ is related to the inflection point Tip of dρ/dT, Δ/Tip = 1.5.
