This property only applies when CalculationFrequency is set to Asynchronous.
AsynchronousCalculationDuration determines how much time is used by the CalculationManager to perform pending calculations. Each time the interval specified by AsynchronousCalculationInterval passes, the CalculationManager will begin performing any neccessary calculations. If there are still calculations pending when the time expires, then some calculations will be left in a dirty state until the next time PerformCalculations is called or the Interval passes again.
To force all calculations to be completed each time the Interval passes, set this property to 0.
