Additional Parameter for Statistical
Calculation
The additional parameter for statistical calculations determines whether
the calculation starts only at the first complete interval. It is useful in
sum calculations, where the calculation is not allowed to take place until
the first complete interval begins. You must set this option if, for
example, you have a daily sum of precipitation referring to midnight
and you wish to calculate complete 24-hour periods only. Note,
however, that in such a case you miss the precipitation sum of the first
uncompleted day.

Accumulator Calculation with
Predefined Reset Time
You can use an "Accumulator" option to add a source parameter to the
destination parameter in order to, for example, accumulate annual
precipitation in the system and to reset the calculation at a predefined
moment.
