Resolution Rollup of planned start date of project is based on the property (com.snc.project.rollup_project_start_date), which can also be set from "Project Administration > Settings > Preferences - Project", So irrespective of calculation type is manual or automatic, Planned start date of project is derived based on the above property, while the planned end date is the highest planned date of all tasks.
