Measurements of independent fission product yields from thermal-neutron fission of ²³⁵U, ²³⁹Pu, ²³³U, and ²⁴¹Pu have been compared with expected yields from a semiempirical analytical model. A general correlation between the experimental/theoretical ratio and the distance of the nuclide from Z_p, the most probable charge in a fission product mass chain, has been constructed. This correlation can serve as a basis for assigning uncertainties to theoretical yield estimates.
