It is shown that the (established) method of deriving chain‐length distributions from propagation probabilities is not fully consistent with the Poissonian character of chain propagation if termination is chain‐length dependent: the fluctuation of chain propagation leads to somewhat lower radical concentrations (rates of propagation). The deviation is the more prominent the more important is the role assigned to the shorter one of the two chains involved in the termination process by the model applied.
