I do not quite understand how the following comment comes about “Updated automatically by changing values within child work package #9” work package #8 is parent to work package #9; as a parent it would logically start BEFORE the child. Yet if I edit - say a grandchild - dates, the parents inherit them. This is incorrect for the start date, and debatably false for the end date (maybe the child needs to start when the parent end, maybe it can start beforehand… certainly not before the start of the parent).

In any instance, this child determination of parent dates appears to make the tool impractical.
Or am I mistaken in my approach to this?
