The lowest frequency that should be entered is 1 divided by the total length of the analytical period (e.g., 1/10 for a 10-year analytical period). Any frequency lower than this will be equivalent to a frequency of 1 divided by the length of the analytical period, since the first cohort will not incur the cost a second time within the analytical period, and in all years after year 1, the same new entrants will incur the cost. | The lowest frequency that should be entered is 1 divided by the total length of the analytical period (e.g., 1/10 for a 10-year analytical period).
