Cause And Effect

To prevent the episode from getting boring, whenever they had to do scenes over again, Jonathan Frakes would re-shoot them from different angles and perspectives to give it a fresh twist on the same story.

Throughout all the 'loops' Data states that the starboard nacelle is damaged in the collision, but when watching the impact take place it's clear that the Enterprises port nacelle is the one damaged during impact.

Port is the left and starboard the right, when facing the front of the vessel. The event of the Bozeman striking the Enterprise is viewed from the rear of the Enterprise, clearly showing the damage to the right (starboard) nacelle, thus, Data identifies it correctly.
