The susceptibility series presented by Aharony, Harris, and Meir [Phys. Rev. B 32 3203 (1985)] for the random-field Ising model and dilute antiferromagnet in a field are reanalyzed. This reanalysis utilizes improved methods of power-series analysis, more recent ${P}_{c}$ estimates, and a redefined constant term. We also invoke updated exponent estimates for comparison with our results, and find that new estimates of $\ensuremath{\gamma}$ for the two models are consistent with each other and with the scaling value from the literature estimates.
