Shared and Individual Reporting

The user manual section 4.1.7, section on shared and individual reporting contains no meaningful description of the functional difference in how shared or individual reporting is interpreted by the scheduling engine.  It also potentially infers that this policy applies only to "To Do List" items, which I don't believe is true since it appears to apply to any leaf task.

Can you update your user manual with meaningful information in this regard?

Could you also provide a better description of what shared versus individual reporting is and give some examples?
