This presents new theoretical and practical results derived from the author's (1974) paper on calculating 12D from inoculated packs. The theoretical portion compares methods for estimating the number of surviving organisms and shows that the Halvorson‐Ziegler formula is approximately derivable from the theory given previously. The more practical part shows several examples of what may hapen if the organism death kinetics are shifted‐rather than simple exponential. A new test procedure is outlined that should lead to more reliable estimates of 12D than are now obtained.
