A method is given for choosing the relative counting times for the sample‐in‐container and empty container parts of a fixed‐duration scattering experiment in order to minimize the statistical error on the container‐corrected intensity. The method is applied to angular‐dispersive diffraction experiments, and the effect on the fractional error of mis‐estimating the relative run times is considered.
