The possibilities of computing MPN‐values were evaluated; and a program was developed to run on a small programmable pocket‐calculator. The mean introduction time of the data amounts to 9.4 s and the time needed to key in a significant number and to calculate the MPN‐value can be estimated by the equation: Time (s) = (32/REF) + 92.64. Introducing a REF‐value of one results in a time of two minutes, which is too long to drop the use of tabulated values. The agreement between calculated and tabulated figures is good.
