Also this:
Players must fully resolve each ship’s activation before moving on to the
next ship—this includes fully executing that ship’s maneuver (resolving anycollisions or card effects) and performing all of that ship’s actions. Each shipin a squad must activate, move, and perform its action individually, even if aplayer is moving several ships of the same pilot skill and selecting the samemaneuvers or actions.
This reinforced that the "move them all in a clump at once" and then focus them all approach is not legitimate in a competitive situation.
