AutoCalc keeps you updated.

With the AutoCalc feature is very easy to keep track of complex tasks. It will automatically update all values like percentages and times of its sub tasks. Once a value is changed in a sub-task, all the above tasks will be updated and recalculated with the corresponding values.

You can also disable this feature for each individual task. If it is disabled, no calculation takes place and the values for this task stay as they are.

This function is very powerful for creating time estimates, or to display the project's progress.
