In any public administrative department not actually at war a staff increase may be expected to follow this formula:
x = 2km + p
where k is the number of staff seeking promotion through the appointment of subordinates; p represents the difference between the ages of appointment and retirement; m is the number of man hours devoted to answering minutes within the department; and n is the number of effective units being administered. Then x will be the number of new staff required each year.
Mathematicians will, of course, realize that to find the percentage increase they must multiply x by 100 and divide by the total of the previous year, thus:
100(2km + p) %
